# Explain Magnetic Quantum Number

The Magnetic quantum number refers to the different orientations are called as orbitals. It is denoted by m. The number of orbitals in a particular sub she will within a principal energy level is given by the number of values allowed to m which in turn depends on the value of $iota$. Since magnetism is because of the angular momentum, the value of m depends on the value of $iota$. For a given value of azimuthal, m can have integral values from – $iota$ through 0 to + $iota$ i e , There’s four sub shells. The possible values of m are all integral values from + $iota$ through o to – $iota$, thus making a total of (2 $iota$ + 1) values s subshell :. Here $iota$ = 0, m can have only one value, m = 0. It means that s subshell has only one orbital p subshell :. Here $iota$ = 1, m can have three values, m = +1, 0, -1. This implies that p subshell has 3 orbitals and therefore on. . The possible positions are px, py and pz d subshell :. Here $iota$ = 2, m can have five values, m = +2, +1, 0, -1, -2. This implies that d subshell has 5 orbitals. The possible positions are dx2, dxy, dyz, dx2- y2, dzx f subshell :. Here $iota$ = 3, m have seven values, m = +3, +2, +1, 0, -1, -2, -3. This implies that f subshell has 7 orbitals The values of m can be: $iota$, $iota$ -1, $iota$ -2, $iota$ -3,. . 0, -1, -2, -3. – $iota$. i e. (2 $iota$ + 1) values are possible. The possible values of m are all integral values from +$iota$ through 0 to -$iota$ thus making a total of (2 $iota$ + 1) values. In an atom, the state of each electron is different with respect to the nucleus. In order to define the state of the electron completely, four quantum numbers are used. They are:Principal quantum number. (n)Azimuthal quantum number. ($iota$)Magnetic quantum number. ($m_{iota}$)Spin quantum number. (s)In order to specify energy, size, shape and orientation of the electron orbital, three quantum numbers are required Magnetic Quantum number is the 3rd quantum number in the set of four quantum numbers. This quantum number is used to state the position of electron in the orbital Let us concentrate on Magnetic Quantum Number in this section. . . . . . . . . .
