Question

An element Y has a valency of 4. Write the formula for its :

1. chloride
2. oxide
3. sulphate
4. carbonate
5. nitrate

Answer 1

Formula for the listed compounds are as follows:

1. Crossing the valencies, chloride for the element Y will have the chemical formula YCl₄.
   
2. Crossing over the valencies, oxide for the element Y will have the chemical formula YO₂.
   
3. Crossing the valencies, sulphate for the element Y will have the chemical formula Y(SO₄)₂.
   
4. Crossing the valencies, carbonate for the element Y will have the chemical formula Y(CO₃)₂.
   
5. Crossing  the valencies, nitrate for the element Y will have the chemical formula Y(NO₃)₄.
