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.
The sub-level s of energy that make the o shell is the K-shell.
Maximum number of electrons = 2n2, where n is the number of shell (n = 1 for K, 2 for L, 3 for M, and so on) K shell has 2 electrons maximum L shell has 8 electrons maximum M shell has 18 electrons maximum N shell has 32 electrons maximum O shell has 50 electrons maximum P shell has 72 electrons maximum
The n value for the 6g sublevel is 6. The principal quantum number (n) represents the energy level or shell in the electron configuration. In this case, the electron is in the 6th energy level.
Four sub-shells: s, p, d, f . Only artificially / theoretically in quantum mechanics there is a 5th sub shell 'g' and maybe 'h' is the 6th

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.

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).
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.
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.
they are both the same meaning

The sub-level s of energy that make the o shell is the K-shell.
Ammonia is a molecule (NH3) and not an atom.
N-Sub happened in 1000.
