Identify the group number of following oxides/hydrides in Mendeleev
periodic table:
i) R2O3 ii) R2O iii) RO2 iv) RH2 v) R2O7 vi) RH3

The oxides or hydrides are formed by exchange of valency between the two atoms involved. The group of the atom bonded to oxygen or hydrogen in the binary compound can be deduced by considering the subscript attached to the oxygen or hydrogen atom.

Now let us take the journey;

R2O3- refers to an oxide of a group 13 element, eg Al2O3

R2O - refers to an oxide of group a group 1 element e.gNa2O

RO2 - refers to an oxide of a group 14, 15 or 16 element such as CO2, NO2 or SO2

RH2 - refers to the hydride of a group 12 element Eg CaH2

R2O7 - refers to an oxide of a group 17 element E.g Cl2O7

RH3- refers to a hydride of a group 13 element E.g AlH3

Identify the group number of following oxides/hydrides in Mendeleev periodic table: i) R2O3 ii) R2O iii) RO2 iv) RH2 v) R2O7 vi) RH3
