Answer 1

Answer:

$\bold\red{Sulphur}$

• Atomic Number = 16

• Symbol = S

• Atomic Mass = 32 amu

• Electronic Configuration = $\bold{1{s}^{2}2{s}^{2}2{p}^{6}3{s}^{2}3{p}^{4}}$

Assertion:-

• Electrons in 3p suborbitals($\bold{4\:{e}^{-}}$) are different from those in 2p suborbitals($\bold{6\:{e}^{-}}$).

Reason:-

• 2p suborbitals come before the 3p suborbitals in electron filling.

• 2p suborbitals gets filled first, and it can accomodate 6 electrons , thus ,6 electrons are filled.

• 3p suborbital has also 6 electron accomodation power , but, there are only 4 electrons left to be filled.
