Isotopes Integrated Science

Isotopes Atoms of the same element with different numbers of neutrons. If they have different numbers of neutrons then they have different mass numbers.

Examples Find the number of protons, neutrons, and electrons for each.

How to name isotopes!! Carbon-12 Carbon-14 12 is the mass number 14 is the mass number How many protons, neutrons, and electrons does Carbon-12 have? How many protons, neutrons, and electrons does Carbon-14 have?
