## Definition of the noun Atomic orbital

What does Atomic orbital mean as a name of something?

**noun**

- [
*quantum*] [*chemistry*] The quantum mechanical behaviour of an electron in an atom describing the probability of the electron's particular position and energy. - A particular atomic orbital associated with a given set of quantum numbers.

## Explanation

**Atomic orbital**: An atomic orbital is a mathematical function that describes the wave-like behavior of either one electron or a pair of electrons in an atom. This function can be used to calculate the probability of finding any electron of an atom in any specific region around the atom's nucleus. The term may also refer to the physical region or space where the electron can be calculated to be present, as defined by the particular mathematical form of the orbital.

- also known as 原子轨道

### A Dictionary of Science (2017)

**the nucleus – an atomic orbital** (see illustration). Alternatively, the orbital can
be thought of as an electric charge distribution (averaged over time). In
representing orbitals it is convenient to take a surface enclosing the space in
which the electron is likely to be found with a high probability. The possible
atomic orbitals correspond to subshells of the atom. Thus there is one s-orbital for
each shell (orbital quantum number l = 0). This is spherical. There are three p-
orbitals (corresponding ...
