Principal Quantum Number: (n), integral values 1, 2, 3 and so forth,  describes the CLOUD SIZE, The larger the value of n, the larger the cloud size, Energy levels closer to the nucleus have lower energy., The maximum number of electrons possible in a given shell is 2n2 , The larger n is, the greater the average distance of an electron in the orbital from the nucleus and therefore the larger (and less stable) the orbital., azimuthal or angular momentum quantum number: (ℓ) , tells us the “shape” of the orbital, sublevel which the electron is said to occupy., It is also an integer, but its values are limited to a range of 0 to n-1., , Magnetic Quantum Number: (mℓ), describes the orbital orientation in space., , , Spin Quantum Numbers: (ms), indicates the spins of the electrons, two possible values, +1/2 and -1/2, (+) and (-) signs only refer to the orientation of the spin,
