The outer shell of the atoms in Group D will always be 1 or 2 s orbital electrons. Irregularities occur with Cr where it is s1d5, not s2d4 and in Group 11 metals it is s1d10 not s2d9 so that the d-subshell is complete at Group 11.
It depends on the particular atom in question. Any of those subshells can make up the outer shells of atoms. Examples: In Mg, the outer shell is the 2s subshell. In P, the outer shell is the 3p subshell. In Fe, the outer shell is the 3d subshell, etc.
an atom has different energy orbitals: s, p, d, and f. each orbital can hold two electrons. the outside energy or highest energy levels of electrons is called the valence shell or valence electrons. for an atom to be stable it wants the electron configuration for the valence shell to be "s2, p6." to answer your question the outer level of an atom can hold 8 electrons. it is called the valence shell.
Magnesium, in the second group, can either gain six electrons or lose two electrons to achieve a full outer shell.
The most stable configuration is when the entire shell is full (noble gas configuration). Next best is when a specific orbital (s, p, d, f, etc.) is completely full, even if the shell is not complete. Next best after that is when a specific orbital is exactly half full.All atoms would like to attain electron configurations like noble gases, i.e., have completed outer shells. Atoms can form stable electron configurations like noble gases by losing electrons, gaining electrons and sharing electrons. For a stable configuration each atom must fill its outer energy level. In the case of noble gases there will be eight electrons in the valence (outer most) shell (with the exception of He which has two electrons). Atoms that have 1, 2 or 3 electrons in their outer levels will tend to lose them in interactions with atoms that have 5, 6 or 7 electrons in their outer levels. Atoms that have 5, 6 or 7 electrons in their outer levels will tend to gain electrons from atoms with 1, 2 or 3 electrons in their outer levels. Atoms that have 4 electrons in the outer most energy level will tend neither to totally lose nor totally gain electrons during interactions and thus they tend to share electrons.

The d-block elements have two electrons in their outermost s sublevels. The group 3 elements have one d electron in their outermost d sublevel, the group 4 elements have two d electrons, adding one additional d electron with each subsequent group until group 12 in which the elements have ten d electrons.
d
you lick it off;D
Technically He and neon have full outer shells, 1s2 and 2s2 2p6 resoectivelly. Theh heavier noble gases all have the ns2, np6 outer shell which confers stability, even though it is not full. Argon for instansce with 3s2 3p6 outer shell has the 3 d orbitals unfilled

The answer is Valence Electrons. Atoms want a full number of electrons in their outer shell, which is why atoms with only one electron missing from their outer shell are most reactive, because they are close to completing that shell. Electrons as such are half-spin particles or fermions. A single particle electron orbital (intended as a solution of a 1-D Schrödinger equation) with occupancies 0 and 1 can have 2 allowed quantum states. Electrons are seen as indistinguishable particles in quantum mechanics. In other words electron 1 is the same as electron 2. We can then state that any electron of appropriate energy will be able to occupy the outermost shell of an element.
Similar it that they have 10d (full d) electrones + 1s electrone
