Alpha decay, beta decay, and gamma decay.

Front

What is an alpha particle?

Back

An alpha particle consists of 2 protons and 2 neutrons, equivalent to 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 a nuclear equation?

Back

A nuclear equation shows the transformation of one element into another through radioactive decay.
