Reason why there are many lines in an atomic spectrum is becausea)All ...
Lines in the spectrum were due to transitions in which an electron moved from a higher-energy orbit with a larger radius to a lower-energy orbit with smaller radius. The orbit closest to the nucleus represented the ground state of the atom and was most stable; orbits farther away were higher-energy excited states.

Reason why there are many lines in an atomic spectrum is becausea)All ...
Explanation:
Atomic spectra are unique patterns of bright lines or bands of colors produced by atoms when they are excited and then return to a lower energy state. These spectra are used to identify elements and study their energy levels.
The reason why there are many lines in an atomic spectrum is because there are many atoms in different states of excitation making transitions to different states. Let's break down the options to understand why option C is the correct answer.
a) All atoms are in the same excited state and make transition to the same state:
If all atoms were in the same excited state and made transitions to the same state, we would observe only one line in the spectrum. This is not the case as we observe multiple lines in the atomic spectrum.
b) There are many atoms in different states of excitation making transition to the same state:
If there were many atoms in different states of excitation making transitions to the same state, we would observe a few lines in the spectrum. However, this does not explain the presence of many lines in the atomic spectrum.
c) There are many atoms in different states of excitation making transition to different states:
This option correctly explains the presence of many lines in the atomic spectrum. When atoms are excited, they absorb energy and move to higher energy states. When they return to lower energy states, they release the absorbed energy in the form of light. Each transition from a higher energy state to a lower energy state corresponds to a specific wavelength or color of light. Since there are many atoms in different states of excitation, each making transitions to different states, we observe multiple lines in the atomic spectrum.
d) All atoms are in the same excited state and make transition to different states:
If all atoms were in the same excited state and made transitions to different states, we would observe a few lines in the spectrum. However, this does not explain the presence of many lines in the atomic spectrum.
Therefore, the correct answer is option C - there are many atoms in different states of excitation making transitions to different states, which results in the presence of many lines in the atomic spectrum.
