Question

the _________________ is the electron - containing main energy level with the highest principal quantum number. electron configuration spin quantum number highest occupied level inner - shell electrons

Explanation:

• Electron configuration refers to the arrangement of electrons in an atom, not a specific energy level.
• Spin quantum number describes the spin of an electron, not an energy level.
• Inner - shell electrons are electrons in lower - energy levels, not the highest.
• The highest occupied level is the electron - containing main energy level with the highest principal quantum number.

Answer:

highest occupied level
