Atomic structure and bonding

The atomic structure and bonding

Introduction:The atomic structure has electrons, protons, and neutrons. They are particles which one of them have a positive, negative and no charge. The middle is the nucleus. Every element has a nucleus. There is two types of bonding called ionic bonding and covalent bonding. There are two bondings that have a different type of process in bonding. First, lets look at the atomic structure.

Electrons, protons and neutrons

Nucleus has positive charge due to the proton in the nucleus. Electrons move around the shells. The number of protons are the number of the atomic number.Atoms have no charge, so the number of protons are equal to the number of electrons.The numbers of neutrons are the number of mass number subtracted by the number of protons.

Example: ChlorineMass number: 35.45Atomic number: 17Protons = atomic number = 17Electrons = protons = 17Neutrons = mass number - atomic number = 18.45
