With the development of quantum mechanics and experimental findings (such as the two slit diffraction of electrons), it was found that the electrons orbiting a nucleus … See more

Orbital notation and subshells
Orbitals have been given names, which are usually given in the form:
$${\displaystyle X\,\mathrm {type} \ }$$
where X is the … See more

The simplest atomic orbitals are those that are calculated for systems with a single electron, such as the hydrogen atom. An atom of any other element ionized down to a single electron is … See more

Simple pictures showing orbital shapes are intended to describe the angular forms of regions in space where the electrons occupying the orbital … See more

The term "orbital" was coined by Robert S. Mulliken in 1932 as short for one-electron orbital wave function. Niels Bohr explained around 1913 that … See more

Because of the quantum mechanical nature of the electrons around a nucleus, atomic orbitals can be uniquely defined by a set of integers … See more

In atoms with one electron (hydrogen-like atom), the energy of an orbital (and, consequently, any electron in the orbital) is determined mainly by $${\displaystyle n}$$. … See more
