Interpretation:
The number of protons and neutrons for each of the Zirconium isotopes needs to be determined.
Concept introduction:
An element consists of three subatomic particles: electrons, protons, and neutrons. The atomic nucleus is made up of neutrons and protons. In any element, the number of protons and electrons is always same but the number of neutrons will be different. Mass of number is calculated by:
Mass number
