metal + non-metal
-an ionic bond occurs between a metal and non-metal
-the metal atoms lose electrons to form positivly charged ions (cations).
-the non-metal atoms gain electrons to for negativly charged ios (anions)
an ion is a charged particle, formed by the loss or gain of electrons
most atoms have incomplete outer electron shells and are unstable.
electrons are transferred from metal atoms to each non-metal atoms to give them full outer shells which are stable
thye metal and non-metal ions are strongly attracted to each other
this is electrostatic attraction is called ionic bonding it form ionic comounds such as sodium chloride
ionic compounds form giant ionic lattices because they are made up of positive and negative electrons and opposites attract causing the lattice effect of positive, negative, positve, negative.
-they form giant lattices
-they dissolve in water
-they conduct electricity
-they have high melting + boiling points
