Question

which has the highest energy 1s or 2s?​

Answer 1

Required Answer:

☑ 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.

Answer 2

Answer:

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.
