Question

this question is from atomic structure ​

Answer 1

Answer:

n=3

l=2

it means subshell is 3d

and the orbital is dzx

so

configuration 1s2 2s2 2p6 3s2 3p6 4s2 3d3

Explanation:

there is a electron with a single spin it means that all orbitals are note fully fillled

and last electron is fillled in 3rd orbital i.e.dzx
