In zinc (Zn), which has an atomic number of 30, the electron configuration is [Ar] 3d² 4s². The 3d subshell is partially filled with 2 electrons, while the 4s subshell is fully filled with 2 electrons. Therefore, the partially filled subshell in zinc atoms is the 3d subshell.
A half filled sub-shell is more stable than other partially filled shells. As an example use Chromium. It should by logic have the following: Sc = [Ar]4s23d1 Ti = [Ar]4s23d2 V = [Ar]4s23d3 Cr should in theory be Cr = [Ar]4s23d4 but it is not. Half filled shells are more stable so the configuration is Cr = [Ar]4s13d5 two half filled sub levels and then Manganese is Mn = [Ar]4s23d5 one full and one half filled level.
Metals with their s and d sublevels partially filled are in transition metals group. For example, in the 4th period, scandium (Sc) has the electron configuration [Ar] 3d1 4s2 with partially filled 3d and filled 4s sublevels.
Elements in period 5 of the periodic table have a total of four sub-shells: s, p, d, and f. The electron configuration of these elements includes the 5s, 5p, and 4d sub-shells, with the 4f sub-shell being filled in the subsequent period (period 6). Therefore, the total number of sub-shells available for elements in period 5 is four.
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
No, the highest energy levels in shells are not always filled first. Electrons fill atomic orbitals starting from the lowest energy level and move to higher energy levels according to the Aufbau principle. This means that within a shell, sub-levels with lower energy (e.g., s before p, p before d) are filled before those with higher energy. Therefore, the filling order is determined by energy levels and sub-levels rather than simply by shell numbers.

It depends whether it can exist alone or has a pair. Some atoms have semi-filled outer shells of electrons (sub-atomic particles) and therefore need to be covalently bonded with another molecule in order to be stable. Others can exist alone.

The second shell of an atom has two sub-shells: the 2s and 2p sub-shells. The 2s sub-shell can hold a maximum of 2 electrons, while the 2p sub-shell can hold a maximum of 6 electrons, allowing the second shell to accommodate a total of 8 electrons.
