Which orbital has the lowest energy?
Understand the Problem
The question is asking about the concept of atomic orbitals and their energy levels. It seeks to identify which specific orbital has the lowest energy among the available orbitals in an atom.
Answer
1s orbital
The 1s orbital has the lowest energy.
Answer for screen readers
The 1s orbital has the lowest energy.
More Information
The 1s orbital is the closest to the nucleus, making it the most stable and lowest in energy.
Tips
A common mistake is mixing up the ordering of higher energy orbitals like 3s, 3p, and 3d.
