Question

An element A has +3 charge and element Y has -1 charge, what will be the chemical formula of the compound formed by them?​

Answer 1

Let Element A be x

• Element Y=y

Now Given in Question that

A has +3Charge so its a cation

$\\ \sf\longmapsto x^{3+}$

Y has -1 charge so its a anion

$\\ \sf\longmapsto y^{-1}$

So lets create compound(Refer to the attachment)

$\\ \sf\longmapsto xy_3$

So the compound is

$\\ \bf\longmapsto AY_3$
