Nuclear Chemistry Test

Alpha, beta, and gamma rays.

A constant interval.

To become more stable.

Cosmic, terrestrial, and internal.

The nuclear force cannot hold the protons and neutrons tight, and the nucleus becomes unstable.

The study of the chemical and physical properties of elements as influenced by changes in the structure of the nucleus.

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

The process by which an unstable atomic nucleus loses energy by emitting radiation.

Alpha radiation consists of helium nuclei, beta radiation consists of electrons or positrons, and gamma radiation consists of high-energy photons.

It is the time required for half of the radioactive atoms in a sample to decay.
