Count atoms and lone pairs to determine the number of domains, do not count bonds Georgetown Independent School District GISD Home The carbon atom forms two double bonds. Like BeH 2, the arrangement that minimizes repulsions places the groups ° apartOnce again, both groups around the central atom are bonding pairs (BP), so COis designated as AX 2 All bonds are represented in this table as a line whether the bond is single, double, or triple. Each double bond is a group, so there are two electron
