Question

d1 electronic configuration correspondence to which of the following terms 1d 2d 3p​

Answer 1

Answer:

Two electrons can occupy any of the five d-orbitals depending on their quantum numbers ml and ms. One possible microstate would be: …if less than half of the subshell is occupied, take the minimum value J = |L − S|;

if more than half-filled, take the maximum value J = L + S;

if the subshell is half-filled, then L will be 0, so J = S.The number of microstates (N) of a system corresponds to the total number of distinct arrangements for “e” number of electrons to be placed in “n” number of possible orbital positions. N = # of microstates = n!/(e!( n-e)!)The ground state of the helium atom has two electrons in the 1s shell, i.e. 1s2. This state has a spin moment S of 0 as the two spins cancel each other. The angular moment L is also 0. The term symbol of the ground state of a hydrogen atom is 1S.Nitrogen atoms have 7 electrons and the shell structure is 2.5. The ground state electron configuration of ground state gaseous neutral nitrogen is [He]. 2s2. 2p3 and the term symbol is 4S3/2..
