Atomic orbitals are 4s, 3s, 3p and 3d. (n + l) values being 4, 3, 4 and 5. Hence 3d has highest energy.

Q. Which of the following set of quantum numbers belong to highest energy?

$n = 4, I = 0, m = 0, s = + 1/2$

$n = 3, I = 0, m = 0, s = + 1/2$

$n = 3, I = 1, m = 1, s = + 1/2$

$n = 3, I = 2, m = 1, s = + 1/2$

Atomic orbitals are 4s, 3s, 3p and 3d. (n + l) values being 4, 3, 4 and 5. Hence 3d has highest energy.

Q. Which of the following set of quantum numbers belong to highest energy?

n=4,I=0,m=0,s=+1/2

n=3,I=0,m=0,s=+1/2

n=3,I=1,m=1,s=+1/2

n=3,I=2,m=1,s=+1/2

Atomic orbitals are 4s, 3s, 3p and 3d. (n + l) values being 4, 3, 4 and 5. Hence 3d has highest energy.

$n = 4, I = 0, m = 0, s = + 1/2$

$n = 3, I = 0, m = 0, s = + 1/2$

$n = 3, I = 1, m = 1, s = + 1/2$

$n = 3, I = 2, m = 1, s = + 1/2$
