Summary

Sample Flashcards

What are isotopes?

Isotopes are atoms of the same element (same number of protons) with different numbers of neutrons. This means they have the same atomic number but different mass numbers.

Why are atoms electrically neutral?

Atoms are electrically neutral because the number of protons (positive charges) equals the number of electrons (negative charges). The positive and negative charges cancel out.
