Subshell letters indicate electron shells. The letters K-Q or numbers 1-7 are called subshell letters. They are placed in superscript form.
-2 Another view the p-shell, one of the 4 sub-shells always represents the outermost 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.
The overall of an atom is a nucleus (protons and neutrons), and 1 or 2 electrons. The rest are for large atoms: an electron shell, electrons, an electron shell, electrons, an electron shell, electrons, an electron shell, electrons, an electron shell, electrons, an electron shell, electrons, an electron shell, electrons.

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.
they are both the same meaning
The sub-level s of energy that make the o shell is the K-shell.

The orbit or electron shell closest to the nucleus is the 1s sub-shell. It can hold 2 electrons before the 2s sub-shell is filled. H and He have their electrons in this shell (the 1s)
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.
The 2d sub energy level does not exist. The first shell to contain a d sub-shell is the third shell: the 3d sub-shell contains a maximum of 10 electrons, with two electrons in each of five different d orbitals.

Because copper loose electron from its penultimate outer shell

Because Fluorine does not have d sub shell.
