The flow of electrons creating an electric charge is known as electricity. It is a fundamental form of energy that powers various devices and systems in our daily lives.
The charge on an electron can be measured as -1e, or -1.602 176 487(40) * 10^-19 Coulombs.Energy of an electron is usually measured in electron Volts (eV). This dimensionally is the same as Joules (energy). The unit Volt is Joules per Coulomb (energy/charge).
An electron is a small particle of matter where energy can be stored. It carries a negative charge and plays a fundamental role in electricity and magnetism.
Electrical charge is quantized. (negative in an electron, as an electron has exactly -1 fundamental unit of charge) The other two would be the energy levels in the atoms and the emitted energy.
The charge of an electron is always −1.602176487(40)×10−19 Coulomb. If an electron is ejected from it's orbital the energy it absorbs is in the form of kinetic energy i.e. how fast it moves. If the electron goes back into an orbital it will only be allowed in an orbital that allows for it's energy. If an atom has an electron and that electron absorbs the energy from an incoming photon it may jump up to a higher orbital or it may be ejected. The ejected electron is the principle of the photo-electric effect.
Mitochondria within the cell creates energy for the cell through Electron cycle.
The charge on an electron is negative (by International Convention) - so electron energy is too
A fundamental law of electrostatics is that opposite charges attract. Electrons carry a negative charge, and protons carry a positive one. The positive charge on the nucleus "captures" the electron and they take up station in an orbital. The electron has too much energy to give it up and collapse into the nucleus, so it hangs out in the electron cloud with other electrons.
