❤.The general formula for the oxidess of group I, II, III and IV are R2O, RO, R2O3 and RO2. Here R represent the element.

❤.The element K belongs to group I of Mendeleev’s peiodic table, thus the formula of its oxide will be K2O.

❤.The element C belongs to group IV of Mendeleev’s periodic table, thus the formula of its oxide will be CO2.

❤.The element Al (aluminium) belongs to group III of mendeleev’s periodic table, thus the formula of its oxide will be Al2O3.

❤.The element Si (silicon) belongs to group IV of Mendeleev’s periodic table, thus the formula of its oxide will be SiO2 .

❤.The element Ba (barium) belongs to group II of Mendeleev’s periodic table thus the formula of its oxide will be BaO.
