Vedclass · Answer

(A) The basic character of metal oxides depends on the electropositivity of the metal. As we move down a group,the metallic character increases,and as we move across a period from left to right,the metallic character decreases. $K$ is an alkali metal (Group $1$),while $Ba$,$Ca$,and $Mg$ are alkaline earth metals (Group $2$). Within Group $2$,the metallic character increases as we go down the group: $Mg Since $K$ is more electropositive than the Group $2$ metals,$K_2O$ is the most basic. Therefore,the correct decreasing order of basic character is $K_2O > BaO > CaO > MgO$.

The decreasing order of basic character of $K_2O$,$BaO$,$CaO$ and $MgO$ is
