An atom with high electronegativity has a small atomic radius relative to its positively charged protons. Having a small number of electron orbitals, or a small atomic radius means that the atom's outermost electrons are relatively close to the nucleus they surround and can therefore experience a...

Electron affinity is defined as the change in the amount of energy experienced when an electron is added to a neutral atom to form a negatively charged ion. Given that the addition of an electron to a neutral atom involves an exothermic reaction, it leads to the release of energy. Why does...
By the end of this article, you will know answers to basic questions like what is ion and example, what is the charge of an electron, what is the charge of a proton, are electrons positive or negative, what does ion mean, what makes an ion, how to find the charge of an ion, what...

In the case of an electron beam, a fraction of incident electrons experience collisions with the nuclei and are backscattered out of the solid before losing significant energy. The corresponding coefficient for energy reflection is therefore proportional to the backscatter yield times the mean energy ...
Electrons have a spin of either +- 1/2. What is the spin of an electron? Electrons are an elementary particle that can either spin up or spin down. A + 1/2 spin is a spin up electron, and a - 1/2 spin is a spin down electron. How do you find the spin quantum number? The...
Hund's rule explains that in each orbital, an electron is present in each axis before the addition of the second electron to the axis. This means, there should be a single arrow in each box of the orbital before going back and adding more arrows. ...
