BONDING CAPACITY OF BERYLLIUM

The electron configuration of Be is Is2 2s2, it has two valence electrons in its ground state. It should not be able to form a covalent bond as the electrons are paired. [Pg.28]

To form a bond, the filled 2s orbital and one of the 2p orbitals combine and give two half-filled sp orbitals. [Pg.28]

Therefore beryllium can have two half filled orbitals and two (unpaired electrons) in its excited state and form the BeH2 molecule with hydrogen. The bond structure of BeH2 is given below [Pg.28]

The BeH2 molecule is formed between Be and H atoms. BeH2 molecule. The direction of orbitals [Pg.29]
