Class 11ChemistryClassification of Elements and Periodicity in PropertiesValency and oxidation state
MediumConsider the following information about elements $P$ and $Q$:
Element Period and Group $Q$ Period $2$,Group $15$ $P$ Period $3$,Group $2$
Then the formula of the compound formed by $P$ and $Q$ elements is:
| Element | Period and Group |
| $Q$ | Period $2$,Group $15$ |
| $P$ | Period $3$,Group $2$ |
Then the formula of the compound formed by $P$ and $Q$ elements is:
- A$PQ$
- B$P_3Q_2$
- C$P_2Q_3$
- D$PQ_2$
