What is the significance of the atomic number in nuclear equations?

Back

The atomic number indicates the number of protons in an atom, determining the element's identity and its position in the periodic table.

Front

What is the significance of the mass number in nuclear equations?

Back

The mass number is the total number of protons and neutrons in an atom's nucleus, indicating its isotopic identity.
