Chemistry - Complete Pblock- Question with Solution | TestHub

Element "A", of 'p'-block shows preferably only two oxidation states " +x " and " +y " (where, " x "& " y " are positive integers & $\mathrm{y}>\mathrm{x}$ )

In one of the oxidation states it achieves pseudo inert gas configuration. Oxide of A is amphoteric and its higher oxidation state is more stable than lower. Element "A" has least IE in its group (upto 6^th period elements only)

Which is/are correct about Element "A"?
