Atoms contain positive and negative charges. Why is the overall charge on an atom neutral?

A. Atoms contain the same amount of protons and electrons, and their charges cancel out.
B. The nucleus of an atom contains neutrons, which keep the positive and negative charges balanced.
C. Atoms are all negatively charged because electrons are on the outside of the atom.
D. Atoms contain the same amount protons and neutrons, and their charges cancel out.

Atoms contain positive and negative charges, the overall charge on an atom neutral because Atoms contain the same amount of protons and electrons, and their charges cancel out.Hence, Option (A) is correct

What is an Atom ?

An atom is the smallest unit of ordinary matter that forms a chemical element.

Every solid, liquid, gas, and plasma is composed of neutral or ionized atoms.

Atoms are extremely small, typically around 100 picometers across.

An atom consists of a positively charged nucleus, surrounded by one or more negatively charged particles called electrons.

The positive charges equal the negative charges, so the atom has no overall charge; it is electrically neutral.Hence, Option (A) is correct
