Is it possible to find the energy of an electron of a particular element in a particular orbit?

It is the difference between the energy levels of the atom. For example, an electron in hydrogen in the ground state (n=1) has an binding energy of -13.6eV. The binding energy at n=2 is -3.4eV, hence for an electron transition from n=1 to n=2 the electron must 'absorb' a photon of energy E = |-13.6 + 3.4 | = 10.2eV. This energy corresponds to the wavelength of a photon in the UV range. Equally, when an electron becomes 'de-excited' i.e. transitions from n=2 to n=1 the electron will emit a photon of the same corresponding energy and hence wavelength. The process becomes a little more complicated if you start looking at the hyperfine structure of hydrogen or other elements in general (as cristo said).anantchowdhary said:What about the energy need for an electron of hydrogen to jump to another orbital?Say when a photon hits it?
Actually, Hydrogen does have spectral lines in the visible range, take a transition from n=3 to n=2 for example; this correspond to an energy of about 1.9eV which results in a wavelength of about 656nm which is in visible [red] light. There are more transitions which occur at the violet end of the spectrum. The energy of IR radiation also 'happens' to correspond to the energies separating the quantum states of molecular vibrations (which results in temperature), its not only atoms and electrons that have quantum states...anantchowdhary said:Thanks a lot for the explanation.This might be able to explain why hydrogen is colourless.As Hootenanny said,ultraviolet rays are emitted by an excited hydrogen electron.hence we cannot see it.Is that correct?
Also i have another doubt regarding hoot's explanation.If an infrared photon strikes an electron why is heat produced?The energy of the photon is so low that as u said it shouldn't interact with the electron or should have very low probability of interacting
The energy of an electron can be described as the amount of work required to move it from its current state to a desired state. It is also a measure of the electron's ability to do work or create a change.
As per the laws of physics, energy cannot be created or destroyed, only transformed from one form to another. Therefore, there is no limit to the energy of an electron. However, the energy levels of electrons in an atom are quantized, meaning they can only have certain discrete values of energy.
Yes, the energy of an electron can be measured using various techniques such as spectroscopy, photoemission, and tunneling. These methods allow us to determine the energy levels of electrons in different systems.
The energy of an electron determines its behavior in a system. Higher energy levels allow electrons to move faster and with more force, while lower energy levels result in slower and less energetic movement. This energy also determines the stability of an electron in its current state.
No, it is not possible for an electron to have zero energy. According to the Heisenberg uncertainty principle, an electron must always have a minimum amount of energy, known as its zero-point energy. This energy is a fundamental property of particles and cannot be removed.
