BRAINCAKETwo Pairs of Electrons
If there are two pairs of electrons around the atom the molecule is linear with a bond angle of 180°.
An example is Beryllium Chloride BeCl2.
In spite of beryllium chloride being made from a metal and non-metal, beryllium atoms are covalently bonded to chlorine atoms in the gas phase.
