Two groups of electrons around the central atom. two bonding pairs of electrons (single bonds) or two double bond pairs give a linear shape and bond angle of 180 o. In these examples the electron pair geometry is the same as the molecular geometry. H-Be-H. linear shape: gaseous beryllium hydride BeH 2 (Q = H, X = Be). Be is a group 2 element with two outer electrons and so can form two single.
