Among Al2O3, SiO2, P2O3 and SO2 the correct order of acid strength is
SO2 < P2O3 < SiO2 < Al2O3
Al2O3 < SiO2 < P2O3 < SO2
Al2O3 < SiO2 < SO2 < P2O3
SiO2 < SO2 < Al2O3 < P2O3
B.
Al2O3 < SiO2 < P2O3 < SO2
While moving along a group from top to bottom acidic nature of oxides decreases and along a period left to right, acidic nature increases.

What type of bonding would you expect between:
(i) a metal and a non-metal
(ii) a non-metal and another non-metal?
Give reasons in one or two sentences for the observation that in their compounds non-metals form anions and not cations.
