What is nuclear radiation?

Back

Nuclear radiation is the emission of particles and energy from the nucleus of an unstable atom as it decays.

Front

What are the three main types of nuclear radiation?

Back

The three main types of nuclear radiation are alpha particles, beta particles, and gamma rays.

What is an alpha particle composed of?

Back

An alpha particle is composed of 2 protons and 2 neutrons, essentially a helium nucleus.

Front

What is a beta particle?

Back

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

Front

What is gamma radiation?

Back

Gamma radiation is a form of 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 a half-life?

Back

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

How do you balance a nuclear equation?

Back

To balance a nuclear equation, ensure that the sum of atomic numbers and mass numbers is equal on both sides.
