belongs to any one of the groups IA, IIIA and VA
The oxide of X is amphoteric, the oxide of Y is
highly acidic, and the oxide of Z is highly basic,
Identify the groups to which these elements X, Y,
Z belong to​

Answer 1

Answer:

element X belongs to IIIA, Y belongs to VA and Z belongs to IA

Explanation:

Oxides of metals are basic while the oxides of non-metals are acidic. As we move from left

to right in a period, bthe basic character of oxides decreases while the acidic character

increases. Thus, element X belongs to IIIA, Y belongs to VA and Z belongs to IA
