Describe the energy levels in the quantum mechanical model of the atom. How does the spacing change as the energy levels get further from the nucleus?

Answer 1

In the quantum-mechanical model of an atom, electrons in the same atom that have the same principal quantum number (n) or principal energy level are said to occupy an electron shell of the atom. Orbitals define regions in space where you are likely to find electrons.
