What is the mass number (A) in nuclear notation?

Back

The mass number (A) is the total number of protons and neutrons in the nucleus of an atom.

Front

How do you calculate the number of neutrons in an isotope?

Back

Number of neutrons = Mass number (A) - Atomic number (Z).

What is gamma decay?

Back

Gamma decay is a type of radioactive decay where an unstable nucleus releases energy in the form of gamma rays without changing its number of protons or neutrons.
