Types of Radioactive Decay

Front

What is Alpha Decay?

Back

A type of radioactive decay where an atomic nucleus emits an alpha particle (2 protons and 2 neutrons), resulting in a new element with a lower atomic number.

Front

What is Beta Decay?

Back

A type of radioactive decay in which a beta particle (an electron or positron) is emitted from an atomic nucleus, transforming a neutron into a proton or vice versa.

Front

What is Gamma Radiation?

Back

High-energy electromagnetic radiation emitted from a nucleus during radioactive decay, often accompanying alpha or beta decay.

Front

What is a Half-Life?

Back

The time required for half of the radioactive atoms in a sample to decay into a more stable form.

Front

How do you calculate the remaining percentage of a radioactive isotope after one half-life?

Back

50% of the original amount remains.

Front

How do you calculate the remaining percentage of a radioactive isotope after two half-lives?

Back

25% of the original amount remains.

What is the difference between Alpha and Beta Decay?

Back

Alpha decay involves the emission of alpha particles, while beta decay involves the emission of beta particles (electrons or positrons).
