Chemistry- Covalent Bonding

Covalent Bonding

When atoms share pairs of electrons, they form covalent bonds. These bonds between atoms are strong. Covalently bonded substances may consist of small molecules. (you must be able to recognise that common substances consist of small molecules from their chemical formula). Some covalently bonded substances have very large molecules, such as polymers. Some covalently bonded substances have giant covalent structures, such as diamond and silicon dioxide.

When non-metal atoms bond together, they share pairs…
