What’s in a name? The importance of an argon-equivalent atom

article An electron can have two states, an electric state and an anti-electron state, but a molecule’s charge can change between these states depending on how it interacts with other molecules.The electrons in an electron-coupled device (ECD) can be charged, neutral, or negative.If an electron is charged and the molecules it interacts directly with are […]

How to use electron cloud to calculate charge of electron

The energy of an electron is related to the energy of its nucleus, but it’s a bit trickier to calculate than the mass of the electron itself.To do that, physicists need to look at the electron’s charge, which is defined as the amount of energy that can be transferred by one electron to another.To calculate […]
