1.	If M is element of group 2 and X is elements of group 17, then which type of compound will be formed ?
Answer» `MX_(2)` `MX` `M_(2)X` `M_(2)X_(3)` Solution :An element of group `-2^(nd)` has tendency to lose 2 electrons and achieve oxidation state `+2` eg. `MG to Mg^(2+) " or " M to M^(2-)` An Element of group-17 gains 1 electron and - 1 state is ATTAINED in compounds of it. eg. `CL to Cl^(-) " or " X to X^(-)` The compounds formed between `M^(2+) " and " X^(-) " are " MX_(2)`
