Compare the energies of 1s and 2s subshells- Which one has greater energy-

Question

Toppr Admin · Accepted Answer

-1s-lt-2s-2s- orbital has greater energy than -1s- because it-s -n- l- value is -2- which is more than -n-l- value for -1s- orbital- If two subshells or orbitals have the same -n- l- value- the subshell or orbital with lower -n- value will have lower energy-

Compare the energies of $$1s$$ and $$2s$$ subshells. Which one has greater energy?

$$1s<2s$$
$$2s$$ orbital has greater energy than $$1s$$ because it's $$n+ l$$ value is $$2$$ which is more than $$n+l$$ value for $$1s$$ orbital. If two subshells or orbitals have the same $$n+ l$$ value, the subshell or orbital with lower $$n$$ value will have lower energy.
