Front

What are isotopes?

Back

Isotopes are variants of a chemical element that have the same number of protons but different numbers of neutrons, resulting in different mass numbers.

What is the atomic number of an element?

Back

The atomic number is the number of protons in the nucleus of an atom, which determines the element's identity.

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

Back

To find the number of neutrons, subtract the atomic number from the mass number (Neutrons = Mass Number - Atomic Number).
