What happens when the number of neutrons in an atom changes?

Changing the number of neutrons creates an isotope, a variation of the same element with a different mass number.

New cards

What are isotopes?

are atoms of the same element with the same number of protons but different numbers of neutrons, resulting in different mass numbers.

How is the atomic mass of an element calculated?

The atomic mass is a weighted average of an element's naturally occurring isotopes, considering their relative abundances.
