select all the circumstances in which a hydrogen atom would be unable to absorb a photon.
the electron is in the lowest energy level.
the photons energy does not match the energy difference between two electron orbitals.
the atom has lost its electron.

Explanation:

• For the first option, an electron in the lowest - energy level can still absorb a photon if the photon has the right energy to move it to a higher level.
• For the second option, a hydrogen atom can only absorb a photon if the photon's energy matches the energy difference between two electron orbitals. If it doesn't match, absorption can't occur.
• For the third option, if the atom has lost its electron, there is no electron to absorb the photon's energy for a transition.

Answer:

The photon's energy does not match the energy difference between two electron orbitals.
The atom has lost its electron.
