Nuclear Chemistry Review

Front

What is a fission reaction?

Back

A fission reaction is a nuclear reaction in which the nucleus of an atom splits into two or more smaller nuclei, along with the release of energy.

Front

What is a fusion reaction?

Back

A fusion reaction is a nuclear reaction in which two light atomic nuclei combine to form a heavier nucleus, releasing energy in the process.

What do isotopes of an element have in common?

Back

Isotopes of an element have the same number of protons but different numbers of neutrons.

Front

What is the atomic number of an element?

Back

The atomic number is the number of protons in the nucleus of an atom, which determines the element's identity.

Front

How do you balance a nuclear equation?

Back

To balance a nuclear equation, ensure that the total number of protons and neutrons is the same on both sides of the equation.

Front

What is an alpha particle?

Back

An alpha particle consists of 2 protons and 2 neutrons, and is emitted during alpha decay.

Front

What is a beta particle?

Back

A beta particle is a high-energy, high-speed electron or positron emitted during beta decay.

Front

What are gamma rays?

Back

Gamma rays are high-energy electromagnetic radiation emitted from the nucleus of a radioactive atom.

Front

What is radioactive decay?

Back

Radioactive decay is the process by which an unstable atomic nucleus loses energy by emitting radiation.

Front

What is half-life?

Back

Half-life is the time required for half of the radioactive atoms in a sample to decay.
