1.	Two elements P and Q combine to form a compound. If P has 2 and Q has 6 electrons in their outermosrt shell, what will be formula of the compound formed ?
Answer» PQ `P_(2)Q` `P_(2)Q_(3)` `PQ_(2)` Solution :Valence electrons in P is 2, Valence electrons in Q is 6 . `P - 2E^(-) to P^(2+)` `Q + 2e^(-) to Q^(2-)` SINCE both showa valency of 2, the formula for the compound will be PQ.
