How many orbitals are found in the d sublevel?
We can derive this from knowing that the atomic orbitals each exist in accordance with angular momentum quantum number
#l = 0 -> s#orbital
#l = 1 -> p#orbital
#l = 2 -> d#orbital
Additionally, what we have associated with
#m_l = 0, pm 1, pm 2, . . . pm (l-1), pm l#
#color(blue)(m_l = -2, -1, 0, +1, +2)#
That indicates that five orbitals are available in the
Furthermore, from knowing that the spin quantum number
Therefore, the total number of electrons in five orbitals can be a maximum of 10.
