Define ‘valency’ of an ion.

CO is an unsaturated compound because all the valencies of carbon are not satisfied and forms addition compounds e.g. It forms carbonyl sulphide (COS ) with sulphur, carbonyl chloride ( phosgene COCl_(2) ) with chlorine, sodium formate with NaOH , methyl alcohol with H_(2) in the presence of ZnO//Cr_(2)O as catalyst) A overset("Red hot coke")(rarr)CO overset(Cl_(2))(rarr)C overset(H_(2)O)(rarr)2HCl+A . The compounds A and C are
