why can't carbon form ionic bonds? explain - help please!!!
carbon cant form ionic compounds...because for that it har to either loose 4 electrons or gain 4 electrons (since its valency is 4)...but it cant do either of them... because of the small size of its atom the bonds are very strong and eletrons are strongly held and to remove these electrons a lot of energy would b required...so it cant loose electrons due to energy considerations .... in the second case it cant gain 4 more electrons becouse of the strong forces of repulsion from the already present electrons...
