C1 1.2 Chemical bondings

There are three types of chemical bondings –

IONIC BONDING:

  • The bonding between non-metal and metal
  • Happens between oppositely charged ions
  • Electrons are transfered
  • Strong intermolecular forces

COVALENT BONDING

  • The atoms share a pair of electrons
  • There is a electrostatic force which is very strong
  • The intermolecular force is very weak
  • Happens between non-metal and non-metal

METALLIC BONDING

  • Happens between metal and metal
  • There is a sea of electrons, electrons are free to move around
