What is a quantum shell?

The quantum shell or the principle shell (represented by an integer known as the principle quantum number, n) are orbits found in an atom. It is arranged as n=1, n=2, and so forth, n=1 being closest to the nucleus. As the numbers increase, so do the energy. Each quantum shell is an orbit, and in the orbits exist sub-orbitals. Please see sub-orbitals for more details.

Which quantum number is also called sub-shell quantum number?

The azimuthal quantum number (l) is also known as the sub-shell quantum number. It represents the sub-shell of an electron within a given energy level. The value of l determines the shape of the orbital (s, p, d, f).


How can you tell the doffermce between 2s subshell and 2p subshell?

You can tell the difference between a 2s sub-shell and 2p sub-shell from their energy levels, because a 2p sub-shell is a higher energy level than a 2s sub-shell.


Why is 2d1 not possible?

A break down of 2d1:2 = the quantum energy level or electron shell denoted as 'n'd = the sub-shell of the energy level (known as a degenerate level)1 = the number of electrons occupying the sub-shell.Through extensive research by scientists, no known element has a d sub-shell in the second (n=2) energy level. In fact, the d sub-shell does not appear until the fourth period (fourth row).The first d sub-shell is known to be in the third energy level (therefore the first energy level with this sub-shell is 3d, but not 2d).Transition metals are the elements known to fill the d sub-shells. The first transition metal in the periodic table is scandium (Sc) with the electron configuration of [Ar]4s23d1.The reasons for the formation of sub-shell of d is beyond my knowledge and the scope of basic chemistry.
