Question

three elements x y and z are present in the third period of the periodic table.Element x forms an acidic oxide.element Y forms an basic oxide,and element Z orms an amphoteric oxide.Which group of the periodic table is Z likely to be present?

Answer 1

Since Y forms the basic oxide, so it will be a metal this is because metals usually form basic oxide.

In the given modern periodic table, the non-metals are on the right side and metals are on the left side.

Now, as Z forms the amphoteric oxide it will belong to the aluminium group no.13.
