Magnetic quantum number. The magnetic quantum number
distinguishes the orbitals available within a subshell, and is used to
calculate the azimuthal component of the orientation of orbital in
space. Electrons in a particular subshell (such as s, p, d, or f) are
defined by values of ℓ (0, 1, 2, or 3).
magnetic quantum number - also known as the third quantum number
- subshells, and orbitals, and their relationships to one another. The
magnetic quantum number tells us about the
orbital that an
electron occupies - it determines how many orbitals there are as well as
their orientation within a subshell. Its symbol looks like this
In order to keep things clear going forward, let's review a few key terms.
Orbitals are regions in space that are occupied by electrons.The electrons are found in shells surrounding the nucleus. The shell that an electron occupies is defined by the
principal quantum number or the
first quantum number. These shells are further divided into
subshells. Subshells can be s, p, d or f. The subshells that an electron occupies are defined by the
angular momentum quantum number or the
secondary quantum number.
