3d^6
Six electrons in the outer shell.
In the atom of Zinc (Zn), there are 10 electrons. Out of these 10 electrons, there are 0 electrons in the 3d orbital. Zn has a configuration of [Ar] 3d10 4s2.
One Mn atom contains 5 electrons in it's 3d subshell, all of which are unpaired.
Titanium atoms have 22 electrons and the shell structure is 2.8. 10.2. The ground state electron configuration of ground state gaseous neutral titanium is [Ar]. 3d2.
The M shell can hold a maximum of 18 electrons. This shell consists of three subshells: 3s, 3p, and 3d. The 3s subshell can hold up to 2 electrons, the 3p subshell can hold up to 6 electrons, and the 3d subshell can hold up to 10 electrons.
Potassium (K) is atomic number 19. It has 19 electrons.1s2 2s2 2p6 3s2 3p6 4s1 so it has ZERO 3d electrons. The 3d doesn't receive electrons until you reach scandium (atomic number 21).

Manganese (Mn) has a total of 25 electrons, and its electron configuration is [Ar] 3d^5 4s^2. In the 3d sub-shell, manganese has 5 electrons.
An atom with 31 electrons will have the electron configuration of [Ar] 4s^2 3d^10 4p^1, representing the filling of the electron orbitals up to the 4th energy level. The element with 31 electrons is gallium (Ga), which has 31 protons in its nucleus to balance the electrons.
Potassium (K) is atomic number 19. It has 19 electrons.1s2 2s2 2p6 3s2 3p6 4s1 so it has ZERO 3d electrons. The 3d doesn't receive electrons until you reach scandium (atomic number 21).
There are four (4) source: http://en.wikipedia.org/wiki/Electron_shell (if you go down a little way on the above website then it lists all of the electrons, which is very helpful!)
Ca has 2 electrons in its outermost shell its configuration being 2, 8,8,2 or 1s2, 2s2, 2p6, 3s2 3p6, 4s2 (4s2 fills before 3d becuase of the aufbau principle) He has also got two electrons these fill the first energy level resulting in a stable arrangement. 1s2
A nickel atom has an atomic number of 28, which means it has 28 electrons. Its electron configuration is [Ar] 3d^8 4s^2. In this configuration, the 3d subshell contains 8 electrons, with 2 of them unpaired. Therefore, a nickel atom has 2 unpaired electrons.
In general, when the transition metals lose electrons, the s shell electrons are lost before the d shell electrons. This is because the s electrons are higher in energy when the atom is in its ionized state. For example, in elements like iron (Fe), the 4s electrons are lost first, followed by the 3d electrons. This trend is observed across the periodic table, particularly in transition metals.
6. If you look at the electron configuration of Selenium, it is [Ar]3d^10 4s^2 4p^4, meaning 10 electrons are located in the 3rd shell, and a total of 6 are located in the 4th shell, the highest energy shell. The electrons in the 4s and 4p shells combined are the valence electrons, meaning there are 6 valence electrons on Selenium.
