Question

valence electrons in the elements x and y are 3 and 6 what is the formula of the compound formed from X and Y

Answer 1

x show +1 &y show+4 Formula With X and Y can be only when if we it's valency.

Answer 2

Answer:

The formula of the compound will be [X^2Y^3].

Explanation:

For element X,

number of valence electrons = 3

So, the ionic form of X is = X^+3

( since it will easily lose three electrons than gain five electrons, to attain the stable configuration)

For element Y,

number of valence electrons = 6

So,the ionic form of X is = Y^-2

( since it will easily gain two electrons than losing six electrons, to attain the stable configuration)

To as per the crisscross rule of valence, the charge of 2 X atoms can balance the charge of 3 Y atoms to form a stable compound.

So, the formula of the compound will be [X^2Y^3].
