Which is the correct order of increasing energy of the listed orbitals in the atom of titanium?
As learnt
Electronic Configuration -
The 'd' block elements follow the general configuration .
-
According to the Aufbau Principle, e-s occupy lower energy orbitals before going higher. Electrons are assigned to orbitals in order of increasing value of n+l.
For subshells with some value of (n+l), e-s are assigned first to the sub shell with lower x.
n+l value Therefore, the correct order will be 3s 3p 4s 3d
3s 3+0=3
3p 3+1=4
3d 3+2=5
4s 4+0=4
