Bonding
- Ionic
- Involves the loss or gain of electrons
- REDOX ( Reduction Oxidation )
- OILRIG
Oxidation
Is
Loss of electrons
Reduction
Is
Gain of electrons
- REDOX ( Reduction Oxidation )
- Between Non-Metals and metals
- Non-Metals
Commonly Groups 1+2
- Metals
Commonly Groups 6+7
- Non-Metals
Commonly Groups 1+2
- Charged particles form (ions) because no. of
protons and electrons are no longer equal
- Therefore the + & - particles are strongly attracted -
Electrostatic forces of attraction
- Which gives ionic compound their high melting & boiling points
- Which gives ionic compound their high melting & boiling points
- Therefore the + & - particles are strongly attracted -
Electrostatic forces of attraction
- Common Examples:
- Involves the loss or gain of electrons
- Covalent
- Involves the sharing of a pair of electrons
- So atoms feel like they have a full shell
- So atoms feel like they have a full shell
- Between Non-Metals only
- An example is di-atomic molocules
- H2 - N2 - 02 - Cl2
- H2 - N2 - 02 - Cl2
- An example is di-atomic molocules
- There are strong bonds between the
shared e- and the nuclei of the atoms
- Some examples:
- The forces of attraction or intermolecular forces are very weak
- SO the melting and boiling points are very low as it takes little energy to
break the intermolecular forces
- As A result most molecular substances are a liquid or gas at room temp
- As A result most molecular substances are a liquid or gas at room temp
- SO the melting and boiling points are very low as it takes little energy to

- Involves the sharing of a pair of electrons
- Metallic
- Metallic Bonding:
- The substance is describes as having a sea of delocalised
electrons
- The substance is describes as having a sea of delocalised
electrons
- When bonding occurs the outer electron(s)
become free or delocalised.
- These electrons are not paired to any atom so can flow
throughout the whole substance
- WHich is why metallic compounds conduct electricity
