Covalent Bonding
- Can be represented by a straight
line or dot - and - cross diagram
- Each line represents a shared
pair of electrons
- Dot - and - cross diagrams
- Only need to show the electrons in the
highest occupied energy level
- Only need to show the electrons in the
highest occupied energy level
- Each line represents a shared
pair of electrons
- Some of the properties of molecules
that are formed in this way
- When two non-metal atoms share a
pair of electrons
- The electrons involved are in the
highest occupied energy levels - or
outer shells - of the atoms
- An atom that shares one or more of its electrons
will complete its highest occupied energy level

- Substances with covalent bonds often
form molecules with low melting and
boiling points
- Atoms may form multiple covalent
bonds, that is, share not just one pair of
electrons but two or more pairs
- Atoms of different elements will form either one, two,
three or four covalent bonds with other atoms
- Atoms of different elements will form either one, two,
three or four covalent bonds with other atoms
- Way to work out how
many covalent bonds an
element will form
- Number of covalent bonds is
equal to eight minus the group
number
- Number of covalent bonds is
equal to eight minus the group
number
- Double covalent bonds meaning they have two
shared pairs of electrons and triple covalent bonds
meaning they have three shared pairs of electrons
- Double covalent bond is
represented by a double line
- Triple covalent bond is
represented by a triple line
- Double covalent bond is
represented by a double line
