How many electrons does the 1s orbital hold for an atom of magnesium?

• 1

• 2

• 4

• 6

What is the best description of Hund’s Rule?

• There cannot be two electrons with the same set of 4 quantum numbers

• Electrons fill the lowest energy level before filling higher energy levels

• Electrons in the same orbital must go into different sub-orbitals (shapes) before pairing and the electron must be the opposite spin

• Electrons must have opposite spins

A line spectrum is produced when an electron moves from one energy level

• to a higher energy level

• to a lower energy level

• into the nucleus

• to another position in the orbital

For an electron in an atom to change from the ground state to an excited state,

• energy must be emitted

• energy must be absorbed

• radiation must be emitted

• the electron must make a transition from a higher to a lower energy level
