Atoms in their natural state are neutral because they have an equal number of protons and electrons.

Here's a breakdown:

* Protons: Positively charged particles found in the nucleus of an atom.

* Electrons: Negatively charged particles that orbit the nucleus.

* Neutrons: Neutrally charged particles also found in the nucleus.

Key Concept: Opposite charges attract.

Since protons are positively charged and electrons are negatively charged, they attract each other. In a neutral atom, the number of protons (positive charges) exactly balances the number of electrons (negative charges), resulting in a net charge of zero.

Example:

* A carbon atom has 6 protons and 6 electrons. The positive charges of the protons cancel out the negative charges of the electrons, making the atom neutral.

Note: Atoms can gain or lose electrons to become ions. Ions are atoms with a net positive or negative charge.
