IONIC BONDS - When an atom that wants to give away electron(s) bonds with an atom that wants to take electron(s), so they can both reach octet (8 valence electrons). The atom that gives away electrons and becomes positively charged as a cation. The atom that takes electrons becomes negatively charged as an anion. The opposite attraction and resultant bonding of the two is called an ionic bond. 2. COVALENT BONDS - When atoms who have similar electro negativities bond to share their electrons to pretend they have an octet. O2 is the air we breathe. Its two oxygen atoms bonding to share two sets of electrons. By themselves they only have 6 each. But sharing creates the effect of 16 (or 2 octets). 3. METALLIC BONDS - When metals, who have a willingness to share electrons, pool their electrons together. By donating their electrons, the metals become positively charged and therefore attracted the electron pool. This metallic bonding makes metals malleable and very conductive. Thats why we use metals, such as copper, to conduct electricity.
