ionic bonding + covalent bonding

define ionic bonding

transfer of electrons between a metal and non metal atom.

Metal loses electrons and non metal gains the electron.

what is the force that draws this bond

electrostatic forces because the ions are oppositely charged ions

covalent bonding

where two non metal atoms share electrons

define similar molecular structure

where the covalent bonding are strong, but the forces between each molecule are weak.

what are the characteristics of simple molecular structure

strong covalent bonds

weak forces between molecules

easy to break (low boiling points)

doesnt conduct electricity

giant covalent bonding

millions of atoms bond together forming covalent bonds

characteristics of giant covalent bonding

lots of covalent bonds

high boiling point

very hard

doesnt conduct electricity

characteristics of graphite

weak molecules forces between all

lots of covalent bond

high melting bonds

conducts electricity (because of delocalised electrons)
