Answer 2

Hi

Tip for u whenever you are stuck like this you should always identify valnecy like this

in this case valency of Al is 3 and oxygen is 2

so they are written in criss cross method

that is valency of oxygen will go to Al and valency of Al will go to oxygen

So your answer is this

the element is aluminium oxide with valency of aluminum 3 and that of oxygen is 2

Hope you understood!
