SPS4 #4 MM Nuclear Chemistry

Front

What is a beta decay?

Back

A type of radioactive decay in which an unstable nucleus emits a beta particle (an electron or positron) and transforms into a different element.

Front

What is fission in nuclear chemistry?

Back

A nuclear reaction where a heavy nucleus splits into two smaller nuclei, releasing energy.

Front

What is the product of the nuclear reaction: 14_6C -> 0_-1e + ?

Back

14_7N (Nitrogen-14)

Front

What happens when the number of protons in an atom changes?

Back

The atom becomes a completely different element with different properties.

Front

What is fusion in nuclear chemistry?

Back

A nuclear reaction where two light nuclei combine to form a heavier nucleus, releasing energy.

Front

What is gamma decay?

Back

A type of radioactive decay in which an unstable nucleus releases energy in the form of gamma rays without changing its number of protons or neutrons.

Front

What is a neutron?

Back

A subatomic particle found in the nucleus of an atom, with no electric charge.

Front

What is an isotope?

Back

Atoms of the same element that have the same number of protons but different numbers of neutrons.

Front

What is the atomic number?

Back

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

Front

What is a radioactive element?

Back

An element that has an unstable nucleus and can undergo radioactive decay.
