which of the following statements is true about energy quantization at the atomic level?

the energy of a photon depends on the frequency of the emission.
the energy of a photon depends on the mass of the neutrons and protons.
an electron can only move from a lower energy level to a higher energy level.
an electron may emit or absorb a quarter of a photon during energy level transitions.

The energy of a photon depends on the frequency of the emission.

Explanation:

E = hν  

where E is the energy of a photon, ν   is the frequency of photon and h is Planck’s constant.  

Energy of a photon is quantized and is directly proportional to the frequency of the emission.  

Quantized energy of a photon explained the photoelectric effect. It was proven that light not has wave nature but particle nature as well. This later gave rise to wave particle duality of light waves.

The energy of a photon depends on the frequency of the emission.

Explanation:

Just took the test, good luck to anyone taking it.

your parents i think this could be it

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be
