Q: Answer-What term is used for atoms that have the same number of protons but different numbers of neutrons?

Isotopes are atoms of the same element having the same number of protons that differ in the number of neutrons they possess. This variance in neutron number can affect the atomic mass and stability but does not alter the chemical properties of the element.
