Ionic compounds form when the atoms of a metal combine with the atoms of a non - metal
1.37 Electron transfer
Electrostatic forces are responsible for holding together the atoms in all substances. These forces are known as bonds, chemical bonds.
Chemical bonds are set up when electrons are transferred or shared between atoms. In this section we consider Ionic bonds . These form when atoms of metals transfer electrons to atoms of non-metals. The metal atoms lose electrons and become positive ions. The non - metal atoms gain electrons and form negative ions.
