Nuclear Chemistry-Review

Front

What type of nuclear radiation is emitted by a radioactive source?

Back

Alpha, beta, and gamma are types of nuclear radiation. Alpha radiation consists of helium nuclei.

How do you balance the nuclear equation: 14_6C -> 0_-1e + ?

Back

The balanced equation is 14_6C -> 0_-1e + 14_7N.

Front

What are positively charged particles found in the nucleus of an atom called?

Back

Protons.

Front

If a sulfur atom has 16 protons, 16 electrons, and 16 neutrons, what is its atomic mass?

Back

32 (atomic mass = protons + neutrons).

Front

What is the charge of a neutron?

Back

Neutrons have no charge (neutral).

Front

What is gamma radiation?

Back

Gamma radiation is high-energy electromagnetic radiation emitted from a nucleus.

Front

What is the difference between alpha and beta radiation?

Back

Alpha radiation consists of 2 protons and 2 neutrons, while beta radiation involves the emission of electrons.

Front

What is a half-life in nuclear chemistry?

Back

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

Front

What is nuclear fission?

Back

Nuclear fission is the process of splitting a heavy nucleus into smaller nuclei, releasing energy.

Front

What is nuclear fusion?

Back

Nuclear fusion is the process of combining light nuclei to form a heavier nucleus, releasing energy.
