an electron jumps from energy level to energy level two by absorbing a photon of energy 8eV. What is the most likely energy of the photon that will be emitted by the electron when it moves back down to energy level one
can someone please help me I need this answer
Your post is incomplete. You omitted the energy level from which the electron started. I assume, however, that if it absorbed energy and moved to energy level two it MUST have started at energy level 1. If that is true and it moved to level 2, the most likely transition is from 2 to 1 so it will emit an energy of 8 eV.

To calculate the most likely energy of the photon emitted when the electron moves back down to energy level one, we need to consider the energy difference between the two energy levels.
First, let's find the energy difference between energy level two and energy level one. We'll assume energy level one has a lower energy value than energy level two.
Given that the electron absorbed a photon of energy 8eV to move to energy level two, we can use this information to find the energy difference.
The energy difference between the two energy levels is equal to the energy absorbed. So, the energy difference is 8eV.
When the electron moves back down to energy level one, it will emit a photon with an energy equal to the energy difference. Therefore, the most likely energy of the photon emitted by the electron when it moves back down to energy level one is also 8eV.
