Cobalt has 27 electrons-27 protons and Iron has 26 electrons-26 protons. Which answer is correct?

A) Iron and Cobalt atoms attract since they don't have the same number of electrons, meaning Iron is positively charged and Cobalt is negatively charged.

B) Iron and Cobalt atoms don't attract since their protons and electrons are balanced, meaning both elements are neutral.

B) Iron and Cobalt atoms don't attract since their protons and electrons are balanced, meaning both elements are neutral.

Explanation:

Electrons have a charge of -1 and protons have a charge of +1. If an atom has the same amount of electrons as protons, the overall charge of the atom is neutral (no charge)

Hint: Think of 27 and subtract 27 from that.

27 - 27 = 0
