Question

how many electrons are in an atom of elemental sodium? equal to the number of neutrons equal to the number of protons equal to the number of protons and neutrons done

Explanation:

In a neutral atom, the number of electrons is equal to the number of protons because atoms are electrically neutral (protons have a positive charge, electrons have a negative charge, and their numbers balance out in a neutral atom). Neutrons have no charge, so the number of electrons is not related to the number of neutrons or the sum of protons and neutrons in this context.

Answer:

equal to the number of protons
