Sodium and potassium are placed in the same group of modern periodic table. If the molecular formula of sodium sulphate is Na, So, then decide the molecular formula of potassium sulphate. Give reason for your answer.

Text Solution

Verified by Experts

•  Molecular formula of potassium sulphate is `K_2SO_4`.
•  Because both sodium and potassium have same number of valence electrons as they are present in the same group.
