Seeing light from fireworks means... a
energy is being absorbed by the atoms
b
energy is being released from the atoms
c
protons are moving into higher energy levels.
d
electrons are moving into higher energy levels.

b  energy is being released from the atoms

Explanation:

Seeing light from fireworks implies that energy is being released from the atoms. This is an excitation as the electrons within the atom moves from a higher energy level to a lower energy level.

if two electrons have the same n, the same ℓ, and the same ml, then they are in the same orbital. the pauli exclusion principle states that no two identical fermions (a fancy word for electrons and other subatomic particles like electrons) may occupy the same quantum state in an atom simultaneously.
