WebCheck your A-level specification to find out which shapes you have to KNOW and which ones you need to be able to WORK OUT. Start with two electron pairs, both bonding (eg BeCl 2 ). The electrons spread to opposite sides of the imaginary sphere and so the molecule is LINEAR with a bond angle of 180 o. WebEach metal atom loses these electrons to gain a full outer shell of electrons. The elections become delocalised into a ‘sea’ of negative charge. A positive metal ion is formed when a metal atom loses electrons. An example of a positive metal ion is Na+ or Ca2+. A metallic bond is the attraction between delocalised electrons and positive ions.
