The electron shells are filled in order 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p. Ground state just means the energy level that electron normally inhabits ie its shell. Electrons can be promoted to higher energy levels if the atom absorbs light energy and then the atom will emit that energy as the electrons fall back to their normal state.
Electron Orbitals can form a hybrid in order to achieve a more stable element: sp, sp2, sp3, sp3d, sp3d2
The electron configuration of a transition element in the Bohr model consists of electrons filling the principal energy levels (n = 1, 2, 3, etc.) and sublevels (s, p, d, f). Transition elements have partially filled d orbitals, so their electron configurations typically involve electrons filling the s and d orbitals. For example, the electron configuration of chromium (Cr) in the ground state is [Ar] 3d^5 4s^1.
Gold has a xenon core...[Xe] 6s1, 4f14, 5d10Gold probably follows the same Aufbau exception as the rest of the copper family, where one electron moves from the s to the d to make it filled, while leaving 1 electron in the s-sublevel.
The ion that will have three electrons in a d subshell as a 3+ ion is iron (Fe). In its neutral state, iron has the electron configuration of [Ar] 3d^6 4s^2. When it loses three electrons to form the Fe^3+ ion, it typically loses the two 4s electrons and one 3d electron, resulting in a configuration of [Ar] 3d^5, which means there are three remaining electrons in the d subshell.
[Xe] 4f10, 5d10, 6s2, 6p3 where[Xe] is1s2, 2s2, 2p6, 3s2, 3p6,4s2, 3d10, 4p6,5s2, 4d10, 5p6 note that the s orbitals are filled before the d orbitals to allow for maximum stability of the atom. Electrons will tend to fill orbitals of a lower energy level than those of higher energy levels
The element with that electron configuration is Iron.
The element with the lowest atomic number that contains a half-filled d subshell at its ground state is scandium (atomic number 21). The electron configuration of scandium at ground state is [Ar] 3d^1 4s^2, where the 3d subshell is half-filled with one electron.
The third principal energy level (n=3) has s, p, and d sublevels. In the ground state, the zinc atom has all the s, p, and d sublevels in the n=3 energy level occupied. Therefore, the total number of occupied sublevels in the third principal energy level of a zinc atom in the ground state is 3.

The element with the lowest atomic number that has a complete d subshell at its ground state is Titanium (element 22). In its ground state, Titanium's electron configuration is [Ar] 3d2 4s2, which means the 3d subshell is completely filled with 2 electrons.

An air state. :D
Transition metals have ground-state electron configurations that differ from the predicted ones due to the exchange of electrons between the ns and (n-1)d subshells. This exchange stabilizes the d orbitals, leading to configurations that are closer to half-filled or fully filled d subshells. Examples include chromium ([Ar] 3d^5 4s^1) and copper ([Ar] 3d^10 4s^1).

Excited state is the opposite of ground state in the context of atoms and molecules. Ground state refers to the lowest energy state of an atom or molecule, while excited states have higher energy levels due to the absorption of energy.
Transmission electron microscopes do not form a 3-D image of the surface of a specimen. They are used to visualize internal structures of specimens with a high magnification. If a 3-D image is desired, techniques like tomography can be used with a series of 2-D images taken at different angles to reconstruct a 3-D image.
