* Protons and Electrons: Atoms contain positively charged protons in their nucleus and negatively charged electrons orbiting the nucleus.

* Equal Numbers: In a neutral atom, the number of protons (positive charges) is equal to the number of electrons (negative charges).

* Balance: The equal and opposite charges cancel each other out, resulting in a net charge of zero.

Example: A hydrogen atom has one proton and one electron. These charges balance, making the hydrogen atom neutral.

Important Note: This only applies to unbonded atoms. When atoms bond together to form molecules, they can gain, lose, or share electrons, leading to the formation of ions (charged species).
