3. Which of the following statements explains why atoms are always neutral in charge
Anna35 [415]

D.

They have the same number of protons as electrons.

Explanation:

Protons are found in the nucleus of the atom and have a positive charge while electrons orbit around the nucleus and have a negative charge. Usually, in a neutral atom of an element, the number of protons is equal to the number of electrons. This is why the atom has no charge because the positive and negative charges cancel out. When an atom loses an electron its charge turns positive while when it gains an electron its charge turns negative.
