The correct set of four quantum numbers for the outermost electron of potassium $(Z=19)$ is

Which of the following sets of quantum numbers is not correct?

Write the electronic configuration of an atom with $Z = 16$. How many $p$ electrons are present in it,and how many fully filled and half-filled orbitals does it contain?

The principle which states that electron occupies the available orbitals singly before pairing in any one orbital occurs is known as:

Consider the following statements :
$(a)$ Electron density in the $xy$ plane in $3d_{x^2-y^2}$ orbital is zero.
$(b)$ Electron density in the $xy$ plane in $3d_{z^2}$ orbital is zero.
$(c)$ $2s$ orbital has one nodal surface.
$(d)$ For $2p_z$ orbital,$yz$ is the nodal plane.
Select the incorrect statements $:-$

The element with the electronic configuration $1s^2 2s^2 2p^6 3s^2 3p^6 3d^{10} 4s^1$ is
