Question

Use Mendeleev’s Periodic Table

to predict the formulae for the

oxides of the following elements:

K, C, AI, Si, Ba.​

Answer 1

Explanation:

K is in group 1. Therefore, the oxide will be K2O. C is in group 4. Therefore, the oxide will be CO2. Al is in group 3. Therefore, the oxide will be Al2O3. Si is in group 4. Therefore, the oxide will be SiO2. Ba is in group 2. Therefore, the oxide will be BaO
