Question

How are two atoms of the same element alike?

Answer 1

two atoms of the same element alike

▶They contain the same number of

protons

, positively charged, massive, nuclear particles. This definition allows for the existence of isotopes, whose atoms contain the same number of

protons

(and must do because they are isotopes of the same element), but DIFFERENT numbers of neutrons, neutrally charged, massive

nucular particles
