316561 Correct statement(s) about phosphorus atom is/ are

1 It has 5 vacant orbitals in the valence shell
2 It has 3 unpaired electrons
3 Nine electrons have similar spin
4 All the above
CHXI11:THE P-BLOCK ELEMENTS

316562 Read the Assertion and Reason carefully to mark the correct option out of the options given below.
Assertion :
Both rhombic and monoclinic sulphur exist as \({\mathrm{\mathrm{S}_{8}}}\) while oxygen exists as \({\mathrm{\mathrm{O}_{2}}}\).
Reason :
Oxygen forms \({\rm{p\pi }} - {\rm{p\pi }}\) multiple bonds with itself and other elements having small size and high electronegativity like C,N, which is not possible for sulphur.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
