an electron is a wavelength of energy that orbits a nucleus at the speed of light in an orbital where only one other electron can exist with an opposite spin, the electons in the orbitals in the...
Electrons in the electron cloud of an atom are located at specific energy levels. We cannot say with certainty exactly where the electron is physically located at any given moment, and that's because...
When ionised to have no electrons, the usual notation would be 1s0. However, this is almost never needed, as other information and context will usually imply or define that there are no electrons.
Two bonding pairs of electrons repel each other the least.The order of electron electron repulsive forces is:lp-lp > bp-lp > bp-bp(bp = bonding pair)(lp = lone pair)
