Question

Answer the following questions:

i. An atomic orbital has n = 3, What are the possible values of l and ml.

ii. In which case energy of 2s orbital is lesser, He or Ne?

iii. Which of the following orbitals are possible?

1p, 2s, 2p and 3f​

Answer 1

Answer:

Answer written in explanation. Plz mark as BRAINLIEST if you find it helpful.

Explanation:

i. n = 3

l = 0(s), 1(p), 2(d)

$m_{l}$ = -2, -1, 0, +1, +2

ii. Ne

Energies of the orbitals in the same subshell decrease with an increase in the atomic number

iii. 2s, 2p
