Detailed explanation-1: -When an atom has an equal number of electrons and protons, it has an equal number of negative electric charges (the electrons) and positive electric charges (the protons). The total electric charge of the atom is therefore zero and the atom is said to be neutral.

Detailed explanation-2: -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.

Detailed explanation-3: -Fundamental Subatomic Particles The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus.

Detailed explanation-4: -Atoms of all elements-except for most atoms of hydrogen-have neutrons in their nucleus. Unlike protons and electrons, which are electrically charged, neutrons have no charge-they are electrically neutral.

Detailed explanation-5: -An ion is a charged atom or molecule. It is charged because the number of electrons do not equal the number of protons in the atom or molecule.
