C2 1.1 - Chemical Bonding

Notes from AQA Book:

• When two or more elements react together compounds are formed. The atoms of elements join together by sharing electrons or by transferring electrons to achieve stable electronic structures. Atoms of the noble gases have stable electronic structures. 
• When atoms of non-metallic elements join together by sharing electrons it is called covalent bonding.
• When metallic elements react with non-metallic elements they produce ionic compounds. The metal atoms lose electrons to form positive ions. The…
