Passage VII
According to a simplified model of the hydrogen atom, an electron orbits a proton located at the center of the atom. The electron can exist only in certain orbits, each with a specific radius. When the electron jumps from one orbit to another orbit of smaller radius, the atom emits a packet of energy known as a photon.
The electron jumps shown in Figure 1, which involve the first 6 orbits, result in the emission of 3 types of photons—ultraviolet, visible, and infrared. The energies and wavelengths of the photons emitted due to these jumps are shown in Table 1.

36. According to Figure 1, a hydrogen atom can emit any one of the 3 types of photons when the electron jumps from all of the following orbits EXCEPT:
Your Answer is
Correct Answer is F
Explanation
As can be seen from figure 1, electrons can only transition from orbit 3 to Orbit 2 and Orbit 1, emit visible photon and ultraviolet photon, but cannot emit infrared photon, so choose F
