Nuclear Vocabulary

What is the definition of Half-Life?

• The time for half the radioactive nuclei in any sample to undergo radio active.

• Radioactive decay.

• The number of protons and neutrons.

What is Mass Number?

• Plural for nucleus

• Radiation deflected towards negative plate.

• The number of protons and neutrons in the nucleus of an atoms.

What is Alpha Particle?

• Chemically identical but radioactive.

• A helium nucleus that is emitted from a radioactive atom.
