# what information is needed to determine the energy of an electron in a many-electron atom?

The electron is one of the basic building blocks of matter. Electrons are the particles that carry the electric charge in the nucleus of every atom. You’ve probably heard of the electron-volt and electron-measurement relationships that relate the energy of an electron to the charge of an atom. The electron-measurement relationship is in the same ballpark as the electron-volt one, although the electron-measurement relationship is not as accurate.

The electron-volt relationship is the one used to calculate the energy of an atom in terms of the charge of the nucleus. The electron-measurement relationship is used to calculate how much energy is required to knock an electron off the nucleus. The electron-measurement relationship is used to calculate the energy needed to knock an electron off the nucleus.

The electron-measurement relationship is not as accurate as the electron-volt one, but that doesn’t mean it’s not worth getting as a reference. There is a reason that the electron-volt is called the “electron-volt” relationship. It’s because the charge of the nucleus is a function of the electron-measurement relationship. The charge of the nucleus is the same for both the electron-volt and electron-measurement relationships.

The energy of an electron is equal to the energy of the hole created by the electron’s collision with the nucleus. The energy of the hole is roughly equal to the energy of the hole created by a photon of light. (This is why photons are said to be “light quanta.”) The energy of a hole is the same as the energy of the electron (the hole) minus the energy of the hole created by the electron’s collision with the nucleus.

The physics of what makes an electron and what makes a hole from an electron and a nucleus, is a little more complex. However, we can begin to think of electron-hole pairs as having the same energy as a photon, but the energy of the electron-hole pair is much higher than the energy of the photon.

And since the energy of an electron is much higher than the energy of a hole, the electron will be attracted by the hole in the same way that a photon will be attracted by an electron. We can understand this by thinking of the electron as having a “color” that is defined by the number of energy quanta the electron carries. The color of an electron is determined by the color of the hole it is trying to make.

So what does that mean for the electron and the photon? Well it means that the ratio of the energies of the electron and the photon can be calculated by counting the energy of the electron. That’s a pretty simple thing to do, but it’s not a simple thing to do in practice. The problem is that the energies of the electron and the photon are so close that they can’t be counted directly.

And the problem is that the energy is so close that its actually very difficult to distinguish between them. To do that, we need to know about what the electron radiates. In the case of the electron, the electron radiates the energy which is called the photon, in the case of the photon the electron radiates the energy which is called the photon. The ratio of the energies of the electron and the photon is thus one.

That ratio, one, is called the fine structure constant. It is a constant that has been determined by experiment to be around 106. The trouble is that it is almost impossible to calculate with a very high accuracy, so we had to rely on calculations that are based on the same assumptions as those used to determine other constants.
