Chemical bonding is the force of attraction that holds atoms together to form molecules or compounds. There are two primary types of chemical bonds: ionic and covalent bonds. Both these bonds play a ...

An Ionic bond is formed when one of the atoms can donate electrons to achieve the inert gas electron configuration and the other atom needs electrons to achieve the inert gas electron configuration.

A small piece of sodium metal is placed in a flask of chlorine gas. A little water helps expose the sodium so it can react with the chlorine gas. The reaction releases a lot of heat as the ionic ...

Part of Combined Science Bonding, structure and the properties of matter The outer shells of non-metal atoms gain electrons when they form ions: the ions formed are negative, because they have more ...

A chemical compound is a chemical substance consisting of two or more different chemically bonded chemical elements, with a fixed ratio determining the composition. The ratio of each element is ...

A two-dimensional model for the ionic lattice in sodium chloride Remember that the lattice arrangement is giant - for example, a single grain of salt may contain 1.2 × 10 18 (1,200,000,000,000,000,000 ...
