In atomic physics, a magnetic quantum number is a quantum number used to distinguish quantum states of an electron or other particle according to its angular momentum along a given axis in space. The orbital magnetic quantum number (ml or m[a]) distinguishes the orbitals available within a given subshell of an atom.

Each orbital in an atom is characterized by a set of values of three quantum numbers n, ℓ, and mℓ, which respectively correspond to electron's energy, its orbital angular momentum, and its orbital angular momentum projected along a chosen axis (magnetic quantum number).

The magnetic quantum number, called m l, specifies the z component of the angular momentum for a particular orbital. For example, for an s orbital, l = 0, and the only value of m l is zero. For p orbitals, l = 1, and m l can be equal to –1, 0, or +1.

Aug 14, 2020 · An orbital is the quantum mechanical refinement of Bohr’s orbit. In contrast to his concept of a simple circular orbit with a fixed radius, orbitals are mathematically derived regions of space with different probabilities of containing an electron.

We therefore need a third quantum number, known as the magnetic quantum number (m), to describe the orientation in space of a particular orbital. (It is called the magnetic quantum number because the effect of different orientations of orbitals was first observed in …

Orbitals in Physics and Chemistry is a mathematical function depicting the wave nature of an electron or a pair of electrons present in an atom. The probability of finding an electron around the nucleus can be calculated using this function.

In quantum mechanics, orbital magnetization, M orb, refers to the magnetization induced by orbital motion of charged particles, usually electrons in solids. The term "orbital" distinguishes it from the contribution of spin degrees of freedom, M spin, to the total magnetization.

The shape of the orbital depends on many factors. The most important are the quantum numbers associated with the particular energy state. These are n , the principal quantum number, l , the orbital quantum number, and m , the angular momentum quantum number.

The term "orbital" refers to a wave function for an electron. The quantity ψ 2 (or ψ*ψ for complex wave functions) describes the probability of interacting with the electron at a particular point in space, ( x, y, z ) or ( r , θ, φ ).

Grand Orbital Table. All atomic orbitals with n=10 are presented here. Note that the orbitals with negative m are identical to those with the same magnitude positive m value except for a rotation,and are not shown separately.
