The atomic number of zinc is 30. Its abbreviated electron configuration is [Ar]4s23d10
The full electron configuration is 1s22s22p63s23p64s23d10
(configurations for the atom in its ground state. Ions and excited atoms have different configurations).
Zinc with 2 Valence electrons
The only element with 55 protons is caesium. The electron configuration you gave is xenon's. In order to change the configuration to get 55 protons, you need to add a 6s1. Also, you listed the electron groups in the wrong order. Switch 4s and 3d, and switch 5s and 4d.
Ground state electron configuration of zinc (Zn): [Ar]3d104s2.
Elements in the zinc group of the periodic table, such as zinc (Zn) and cadmium (Cd), have the electron configuration s2d10 in their outermost shell. This configuration results from the filling of the 3d orbital after the 4s orbital is filled.
Noble Gas Notation: [Ar] 3d10 4s2 Electron Configuration: 1s2, 2s22p6, 3s23p6, 4s23d10 Electron Arrangement in Shell: 2, 8, 18, 2
Zinc with 2 Valence electrons
No, that electron configuration does not exist. After the 3p orbital fills with electrons, the next lowest energy orbital is 4s. After 4s contains 2 electrons, then 3d can accept electrons, upto 10. The element with this electron configuration is zinc, one of the transitional metals. Although 3d is full, those electrons can be 'valence' electrons and given to non-metals to form ions, such as Zn+2 or Zn+4. So 3d really acts like a 4th shell orbital and will still be quite reactive even when full. To see just how reactive these electrons are, look at the youtube videos embedded in this site: http://www.chemicool.com/elements/zinc.html.
Sodium (Na) is the element most likely to lose an electron easily. As an alkali metal, it has a single electron in its outer shell, which it can readily lose to achieve a stable electron configuration. This makes sodium highly reactive compared to aluminum (Al), zinc (Zn), and chlorine (Cl), which have different electron configurations and tendencies to lose or gain electrons.

2 electrons. The electron configuration of Zn is 2.8.18.2
The electron configuration for zinc (Zn), which has an atomic number of 30, is 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰. This configuration indicates that zinc has a full 3d subshell and a filled 4s subshell, reflecting its placement in the d-block of the periodic table.
Ground state electron configuration of zinc (Zn): [Ar]3d104s2.
Elements in the zinc group of the periodic table, such as zinc (Zn) and cadmium (Cd), have the electron configuration s2d10 in their outermost shell. This configuration results from the filling of the 3d orbital after the 4s orbital is filled.
An electron distribution that ends in ( s^2 d^2 ) corresponds to the transition metals in the fourth period of the periodic table, specifically zinc (( \text{Zn} )) and its neighboring elements. The electron configuration for these elements typically follows the pattern of filling the ( 3d ) subshell after the ( 4s ) subshell. Thus, an example of such a configuration is for the element titanium, which has the configuration ( [Ar] 4s^2 3d^2 ).
The electron configuration of zinc II is [Ar]3d10, where [Ar] represents the electron configuration of argon (1s2 2s2 2p6 3s2 3p6). This means that zinc II has lost two electrons from its neutral state (Zn) to become Zn2+.

The charge of the Zn ion is typically 2+ or 2. This is because zinc typically loses two electrons to achieve a stable electron configuration.
