Choose the correct answer from the options given below: only
Text Solution
Verified by ExpertsThe correct answer is:
A
For hydrogen atom and one electron species, the energy of orbitals is decided by the value of
principal quantum number. Higher the value of principal quantum number, higher will be the energy of orbital.
4 s 
(E) 
and have orbitals with the lowest energy.
