Atoms are really tiny particles that make up all substances in the universe. An element is made of one type of atom. An atom has a small central nucleus made up of smaller sub-atomic particles called prot...

Ionic: Metal and non Metal bond fomred , Metal DONATES an electron. electrostatic attraction between oppositely charged ions in a chemical compound Covalent: Bond between two non metals (similar electrone...

Reactions are all about the formation and the breaking of bonds between atoms. The formation of bonds within a system causes energy to be released whilst the breaking of bonds requires energy to be applie...

Ionic Bonding 

Ionic bonding occurs between positive ions (cations) and negative ions (anions), which are attracted to each other through their oppisite charges. The resulting comp...

By defintion, Le chatelier's principle states that if a reaction at equilibrium (i.e a reversible reaction) is subject to a change in concentration, pressure or temperature the system will act in a way to...
