Atomic Structure

A positively charged atom is said if the number of positive charges (protons) in the nucleus more than the negative charge (electrons) in the atomic shell that surrounds it. A negatively charged atom is said if the number of positive charges (protons) in the nucleus less than the amount of negative charge (electrons) in the atomic shell.

An atom is said to neutral when in essence there are positive charges (protons) an amount equal to the negative charge (electrons) in the skin.

The simplest atom is the hydrogen atom is only composed of one proton and one electron. Because the same number of protons and electrons, the hydrogen atom is said to be neutral atoms. Helium atoms consist of two protons, two neutrons and two electrons. Due to the number of protons and electrons the same amount, then the helium atom is also said to be neutral atoms.
