Question

atoms always have the same number of: *
protons and neutrons
protons and electrons
none of the above
electrons and neutrons

Explanation:

In a neutral atom, the number of protons (positively charged particles in the nucleus) is equal to the number of electrons (negatively charged particles surrounding the nucleus) because the atom is electrically neutral. The number of neutrons (neutral particles in the nucleus) can vary (isotopes) and doesn't have to be equal to protons or electrons. So atoms always have the same number of protons and electrons in their neutral state.

Answer:

B. Protons and Electrons
