Vedclass · Answer

(C) The element $X$ has an outer electronic configuration of $ns^2np^1$. Since it is in the first short period (Period $2$ or $3$),and considering the valence shell configuration,the element is Boron $(B)$ or Aluminum $(Al)$.For Boron $(B)$,the oxide is $B_2O_3$,and for Aluminum $(Al)$,the oxide is $Al_2O_3$.Both $B_2O_3$ and $Al_2O_3$ are known to be amphoteric in nature,meaning they can react with both acids and bases.

An element $X$ which occurs in the first short period has an outer electronic structure $s^2p^1$. What are the formula and acid-base character of its oxides?
