When determining the formula for a compound, it is important to know the valence numbers of each element. Suppose you want to wr

Damm [24]

Explanation:

The valency of the element is the measure of the combining power of the element with the other atoms when the element forms compounds or molecules.

<u>Thus, valency has to known to find the how the elements have been combined and how many electrons have been lost, gain or shared.</u>

Given that:

Element A has 3 valence electrons and element B has 2 valence electrons. To find the ionic compound, the valency of the cations and the anions are interchanged and are written in subscripts. Thus,

A B

3 2

Cross multiplying, we get the formula : $A_2B_3$
