In What State Must Matter Exist For Fusion Reactions To Take Place??

Fusion reactions take place in a state of matter called plasma — a hot, charged gas made of positive ions and free-moving electrons that has unique properties distinct from solids, liquids and gases.May 10, 2021

In what state must matter exist for fusion reactions to take place group of answer choices?

Fusion energy, relying as it does on the fusion reaction between light nuclei, occurs only when the particles are sufficiently energetic to overcome the Coulomb repulsive force. This requires the production and heating of the gaseous reactants to the high temperature state known as the plasma state.

What is the process in which unstable atomic nucleus emits charged particles or energy or both?

Radioactivity is the process in which an unstable atomic nucleus emits charged particles and energy. Any atom containing an unstable nucleus is called a radioactive isotope, or radioisotope for short. Common types of nuclear radiation include alpha particles, beta particles, and gamma rays.

Which type of nuclear decay produces energy instead of a particle?

Alpha and Beta decay processes produce physical particles. Gamma decay produces gamma rays which are waves and thus no particle change occurs.

What is the process in which an unstable atomic nucleus emits charged particles or energy or both quizlet?

Who was the man to discover radioactivity? The process in which an unstable atomic nucleus emits charged particles and energy. What happens when the composition of an radioisotope changes? The radioisotope undergoes nuclear decay.

Where does nuclear fusion take place?

the sun

In nuclear fusion, two or more small nuclei combine to form a single larger nucleus, a neutron, and a tremendous amount of energy. Nuclear fusion of hydrogen to form helium occurs naturally in the sun and other stars. It takes place only at extremely high temperatures.

What is fusion matter?

It is the reaction in which two atoms of hydrogen combine together, or fuse, to form an atom of helium. In the process some of the mass of the hydrogen is converted into energy. … Thus fusion has the potential to be an inexhaustible source of energy.

Is how we describe any process where the nucleus emits particles or energy?

Radioactive decay is the process in which the nuclei of radioactive atoms emit charged particles and energy, which are called by the general term radiation. Radioactive atoms have unstable nuclei, and when the nuclei emit radiation, they become more stable.

What does not consist of charged particles of matter?

γ-rays are neutral particles.

Which process occurs during radioactive decay?

Radioactive decay (also known as nuclear decay, radioactivity, radioactive disintegration or nuclear disintegration) is the process by which an unstable atomic nucleus loses energy by radiation. A material containing unstable nuclei is considered radioactive.

What is the difference between fission and fusion?

The main difference between these two processes is that fission is the splitting of an atom into two or more smaller ones while fusion is the fusing of two or more smaller atoms into a larger one.

Why do α and β decay produce new elements but γ decay does not?

because alpha and beta are particles whereas gamma is radiation. when alpha and beta particles are released there occurs change in atomic and mass number resulting in new element. in gamma radiation only energy is released and hence no element is formed. hope this helps.

Which type of radioactive decay produces particles with the most mass?

Comparing only the three common types of ionizing radiation, alpha particles have the greatest mass. Alpha particles have approximately four times the mass of a proton or neutron and approximately 8,000 times the mass of a beta particle.

When an unstable atomic nucleus emits?

Radioactivity is the process in which an unstable atomic nucleus emits charged particles and energy. Any atom containing an unstable nucleus is called a radioactive isotope, or radioisotope for short. During nuclear decay, atoms of one element can change into atoms of a different element altogether.

Which type of particle can be emitted by an unstable nucleus quizlet?

A high energy electromagnetic radiation emitted from an unstable nucleus as it changes from an excited state to a ground state. Gamma rays are often emitted immediately after other types of decay occur.

What does it mean for a nucleus to be unstable?


An atom is stable if the forces among the particles that makeup the nucleus are balanced. An atom is unstable (radioactive) if these forces are unbalanced; if the nucleus has an excess of internal energy. Instability of an atom’s nucleus may result from an excess of either neutrons or protons.

Which change takes place in a nuclear fusion reaction?

In a fusion reaction, two light nuclei merge to form a single heavier nucleus. The process releases energy because the total mass of the resulting single nucleus is less than the mass of the two original nuclei. The leftover mass becomes energy.

Where in the sun do fusion reactions happen quizlet?

Nuclear fusion occurs – A process in which particles of an element collide and form a heavier element, such as the fusion of hydrogen into helium that occurs at the Sun’s core.

What takes place during the fusion reactions in the core of the Sun?

In the core of the Sun hydrogen is being converted into helium. This is called nuclear fusion. It takes four hydrogen atoms to fuse into each helium atom. During the process some of the mass is converted into energy.

Is fusion a state of matter?

What is fusion in state?

Fusion occurs when two light atoms bond together, or fuse, to make a heavier one. … At this heat, the hydrogen is no longer a gas but a plasma, an extremely high-energy state of matter where electrons are stripped from their atoms. Fusion is the dominant source of energy for stars in the universe.

How does the state of matter change during the fusion process?

Fusion. Fusion occurs when a substance changes from a solid to a liquid. Prior to melting, strong intermolecular bonds or attractions hold the atoms, molecules or ions that comprise a solid substance tightly together in the solid form.

Where does the energy released in a nuclear reaction come from?

Nuclear energy comes from tiny mass changes in nuclei as radioactive processes occur. In fission, large nuclei break apart and release energy; in fusion, small nuclei merge together and release energy.

Which of the following best describes nuclear fusion reaction?

Nuclear fusion is a kind of nuclear reaction in which two lighter nuclei combine under suitable conditions to form heavier nuclei under suitable conditions. … Hence, the heavier nuclei have greater binding energy than the lighter nuclei. This difference in binding energy is released during the nuclear fusion process.

When a nucleus emits radiation what does it become?

In a nuclear decay reaction, also called radioactive decay, an unstable nucleus emits radiation and is transformed into the nucleus of one or more other elements. The resulting daughter nuclei have a lower mass and are lower in energy (more stable) than the parent nucleus that decayed.

Why does charge exist?

Charge thus exists in natural units equal to the charge of an electron or a proton, a fundamental physical constant. … Atoms of matter are electrically neutral because their nuclei contain the same number of protons as there are electrons surrounding the nuclei.

Where do electrons exist in an atom and what is their charge?

Electrons are found in shells or orbitals that surround the nucleus of an atom and have a negative charge. Their total negative electrical charge is equal to the protons’ positive electrical charge. Protons and neutrons are found in the nucleus.

Which of the following consists of particles of matter?

Matter on Earth is in the form of solid, liquid, or gas. Solids, liquids, and gases are made of tiny particles called atoms and molecules.

Where does neutron radiation occur?

Sources. Neutrons may be emitted from nuclear fusion or nuclear fission, or from other nuclear reactions such as radioactive decay or particle interactions with cosmic rays or within particle accelerators.

What always occurs during a nuclear fission reaction?

Nuclear fission: In nuclear fission, an unstable atom splits into two or more smaller pieces that are more stable, and releases energy in the process. The fission process also releases extra neutrons, which can then split additional atoms, resulting in a chain reaction that releases a lot of energy.

What is the radioactive process?

Radioactivity is the process by which a nucleus of an unstable atom loses energy by emitting particles of ionizing radiation, As each nucleus disintegrates, in its effort to find a more stable combination, it emits a charged particle that, because of its kinetic energy, is capable of penetrating solid material.

Where does fusion occur naturally?


Fusion reactions occur naturally in stars like our sun, where two hydrogen nuclei fuse together under high temperatures and pressure to form a nucleus of helium. Energy is released as electromagnetic radiation such as light, infra-red radiation and ultra violet radiation , which then travels through space.

What conditions are required for nuclear fusion?

Conditions for Nuclear Fusion

  • Fusion requires temperatures of about 100 million Kelvin (approximately six times hotter than the sun’s core).
  • At these temperatures, hydrogen is a plasma, not a gas. …
  • The sun achieves these temperatures by its large mass and the force of gravity compressing this mass in the core.

Does the sun do fusion or fission?

The Sun is a main-sequence star, and thus generates its energy by nuclear fusion of hydrogen nuclei into helium. In its core, the Sun fuses 500 million metric tons of hydrogen each second.
