WebIonic Bonding. When sodium is burned in a chlorine atmosphere, it produces the compound sodium chloride. This has a high melting point (800 ºC) and dissolves in water to to give a conducting solution. Sodium chloride is an ionic compound, and the crystalline solid has the structure shown on the right. WebThe bond formed by the creation of positive and negative ions is called an ionic bond. During the chemical connection of metal and non-metal atoms, one or more electrons of the last energy level of the metal atom are transferred to the last energy level of the non-metal atom. The compound that forms ionic bonds is called an ionic compound.
