**Energy Levels and Electron Transitions**This energy diagram demonstrates the allowed energy levels of an electron in a specific atom. Note that the SI prefix 'zepto' (z) represents \(10^{-21}\). **Energy Diagram Description:**The vertical axis represents energy in zeptojoules (zJ). The diagram shows three energy levels labeled A, B, and C:- Level A is at 200 zJ.- Level B is at 600 zJ.- Level C is at 1000 zJ.A red arrow illustrates an upward transition from energy level A to B.**Table: Energy Level Information**1. **What is the energy of the electron in the ground state?** - The electron's energy in the ground state (A) is 200 zJ.2. **What is the energy of the electron in the first excited state?** - The electron's energy in the first excited state (B) is 600 zJ.3. **If the electron makes the transition shown by the red arrow, from A to B, will a photon be absorbed or emitted?** - A photon will be absorbed.4. **Calculate the wavelength of the photon that would be absorbed or emitted.

The lowest energy level of the electron is known as a ground state. In the given energy level the energy level A is the ground state and the energy levels B and C are the excited states.The energy of the electron in the ground state is given by: The energy of the electron in the ground state is = 300 ZJThe energy of the electron in the first excited state is given by: The energy of the electron in the first excited state is = 750 ZJIn the given transition the electron moves from a lower energy level to a higher energy level, hence the energy is absorbed by the electron.The wavelength of the absorbed photon is given by: for a photon we know that:E=hv = hCλE = energy of photonwhere, v = frequency of the photonC = speed of light=3×108 m/sλ = wavelength of the photonh = plank constant = 6.626×10-34 J.sBy rearranging the above equation we get:λ = hCELet's put the above values into this formula:λ = 6.626×10-34 J.s × 3×108 m/s750-300 ZJλ = 6.626×10-34 J.s × 3×108 m/s450 ZJλ = 6.626×10-34 J.s × 3×108 m/s450×10-19 Jλ = 6.626×10-34 J.s × 3×108 m/s450×10-19 Jλ = 4.417×10-9 mλ = 4.42×10-9 mλ = 4.42 nm
