Valence electrons in the element X are 3 and that in element Y is 6. Most probable compound formed from X and Y is

Options

A $X_2 Y$
B $X Y_2$
C $X_6 Y_3$
D $X_2 Y_3$

Correct answer

D. $X_2 Y_3$

Step-by-step solution

Valence electrons in

\mathrm{X}=3

Valence electrons in

\mathrm{Y}=6

Thus, X is electropositive and Y is electronegative, X can lose three electrons and Y can gain two electrons to attain stable configuration. Hence, X exists as

\mathrm{X}^{3+}

and Y as

\mathrm{Y}^{2-}

and compound is

X_2 Y_3
