A

4p-orbital

B

4f orbital

C

4s orbital

D

4d-orbital

Solution

Verified by Toppr

Correct option is A)

According to the Aufbau principle of electron filling in orbitals, the next shell to be filled after the $3 d$ orbital is the $4 p$ orbital.

Hence, the correct option is $A.$

The $19 t h$ electron in potassium atom enters into $4 s$ orbital and not the $3 d$ -orbital.

$(n + l)$ rule is followed for determining the orbital of the lowest energy state.

The $19 t h$ electron in potassium atom enters into $4 s$ orbital and not the $3 d$ -orbital.

After filling the $4 d$ -orbitals, an electron will enter in:

In multi-electron system (atom or ion), $4 s$ orbital if filled first then $3 d$ orbital is filled

$4 s$ orbital is closer to the nucleus than $3 d$ orbital.

In multi-electron system (atom or ion), $4 s$ orbital if filled first then $3 d$ orbital is filled
