Atomic number of Cr=24 and its configuration is 1s2,2s2,2p6,3s2,3p6,4s1,3d5 or text ! ![ ! ! text Ne text ! !] ! ! text 3s2, text 3p6, text 3d5, text 4s1 because exactly full filled orbitals are more stable than nearly fulfilled orbitals.

Q. Chromium is represented by the electronic configuration:

$[N e] 3 s^{2} 3 P^{6} 3 d^{1} 4 s^{2}$

$[N e] 3 s^{2} 3 p^{6} 3 d^{2} 4 s^{1}$

$[N e] 3 s^{2} 3 p^{6} 3 d^{5} 4 s^{1}$

$[N e] 3 s^{2} 3 p^{6} 4 s^{2} 3 d^{4}$

Atomic number of $C r = 24$ and its configuration is $1 s^{2}, 2 s^{2}, 2 p^{6}, 3 s^{2}, 3 p^{6}, 4 s^{1}, 3 d^{5}$ or $[N e] 3 s^{2}, 3 p^{6}, 3 d^{5}, 4 s^{1}$ because exactly full filled orbitals are more stable than nearly fulfilled orbitals.

Q. Chromium is represented by the electronic configuration:

[Ne]3s23P63d14s2

[Ne]3s23p63d24s1

[Ne]3s23p63d54s1

[Ne]3s23p64s23d4

Atomic number of Cr=24 and its configuration is 1s2,2s2,2p6,3s2,3p6,4s1,3d5 or [Ne]3s2,3p6,3d5,4s1 because exactly full filled orbitals are more stable than nearly fulfilled orbitals.

$[N e] 3 s^{2} 3 P^{6} 3 d^{1} 4 s^{2}$

$[N e] 3 s^{2} 3 p^{6} 3 d^{2} 4 s^{1}$

$[N e] 3 s^{2} 3 p^{6} 3 d^{5} 4 s^{1}$

$[N e] 3 s^{2} 3 p^{6} 4 s^{2} 3 d^{4}$

Atomic number of $C r = 24$ and its configuration is $1 s^{2}, 2 s^{2}, 2 p^{6}, 3 s^{2}, 3 p^{6}, 4 s^{1}, 3 d^{5}$ or $[N e] 3 s^{2}, 3 p^{6}, 3 d^{5}, 4 s^{1}$ because exactly full filled orbitals are more stable than nearly fulfilled orbitals.
