In an atom, an orbital represents

• the most probably location of a proton

• the most probable location of an electron

• the least probably location of a neutron

• photons emitted as electrons move to lower energy levels

An electron occupies the lowest energy orbital possible

• Hund’s rule
• Pauli exclusion principle
• Bohr model of the atom
• Aufbau principle

Electrons that have not been excited are said to be at:

• high level

• base line

• set state

• ground state

Light is emitted when electrons

• move from one atom to another.

• collide with one another, releasing energy.

• move from a lower energy level to a higher energy level.

• move from a higher energy level to a lower energy level.
