How can we work out the number of covalent bonds by using the group number?
The number of covalent bonds is equal to 8 minus the group number.

How is a covalent bond formed?
A covalent bond forms when two non-metal atoms share a pair of electrons. The electrons involved are in the outer shells of the atoms to complete the outer shell.
2 of 6
True or false? Covalent bonds are strong
TRUE! A lot of energy is needed to break them.
3 of 6
What is the arrangement of a giant covalent structure?
Usually arranged into giant regular lattices which are very strong because of all the bonds involved.
4 of 6
How are the atoms joined together in a giant covalent structure?
The atoms are joint to adjacent atoms.
5 of 6
What is a simple molecule?
Simple molecules contain only a few atoms held together by covalent bonds.
