Energy Levels, Orbitals, Spin Quantum Numbers

The major difference between a 1s orbital and a 2 s orbital is that

• the 2 s orbital is at a higher energy level.
• the 2s orbital has a slightly different shape.
• the 1 s orbital can have only one electron.
• the 2s orbital can hold more electrons.
