1. the element pair bond: a bond to make access of non-ferrous metals non-metallic
2. using electron:Arising from the non-metallic elements Try to make yourself to have reached eight electrons, it would work with other non-metallic elements or the elements the same. A single bond and double bond three bond
3. value differences less: EN till does not differ at all.
4. bonding strength:Strong metal bond and bond less than an orange,
5. characteristics of compounds: both State 3 cannot apply electric boiling point. The low melting point
6. sample code Vegas CI2: len bond
