Scandium is a transition element, so it has properties quite different. so instead of having 2-8-8-3 it sends 1 electron to the inner L shell and becomes 2-8-9-2
Potassium.
L-1 electron configuration
D. S-2Electron configuration has to do with the number of electrons, so using a Periodic table, it is easy to find this answer.For example, O-2 has 2 more electrons than usual, so move two spaces to the right, which is neon.For F- , it is the same way. Since it is a minus 1, move one space to the right, which is neon.For Al+3 there are 3 LESS electrons than usual so move back(to the right) 3 spaces, which is neon.For S-2 , the answer to your problem, has the same electron configuration as Argon.For Mg+2 there are 2 less electrons so moving back 2 spaces gives you neon.Remember 'minus' means more electrons so for electron configurations you move forward on the Periodic table for ions with negative charge and backwards if the ion is positive.
2*2 is 4. like 2+2=4
It is like this if you are doing 2 squared you do 2 *2 = 4
The electronic configuration of scandium is [Ar] 3d1 4s2. It has 21 electrons, with the 3d orbital containing 1 electron and the 4s orbital containing 2 electrons.
The electron configuration for scandium is 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^1. Therefore, the three highest-energy electrons in scandium are in the 3d orbital, and the electron notation for these three electrons is 3d^1.
Scandium typically forms a colorless Sc3+ cation in chemical compounds, with a configuration of [Ar] 3d1 4s2. This means that scandium is found in the 3d shell in its most common oxidation state.
The electron configuration of scandium (Sc) is [Ar] 3d1 4s2, indicating that it has 21 electrons arranged in the shells 1s2 2s2 2p6 3s2 3p6 3d1 4s2. Scandium has one electron in the 3d orbital and two electrons in the 4s orbital. This configuration follows the principles of the Aufbau principle and the Pauli exclusion principle.
Americium has similar outer electron configuration to scandium due to their placement in the same group of the periodic table. The outer electron configuration influences an element's chemical behavior, so americium shares more similarities with scandium than with calcium, which is in a different group.
The full electronic configuration for boron is 1s^2 2s^2 2p^1.

The correct electronic configuration of magnesium (Mg) is 1s^2 2s^2 2p^6 3s^2. This configuration represents the arrangement of electrons in the different energy levels and sublevels of an atom of magnesium.
The electronic configuration of Calcium (Ca) is 1s2 2s2 2p6 3s2 3p6 4s2.
The electronic configuration for iodine is [Kr] 4d^10 5s^2 5p^5 2, 8, 18, 18, 7.
Oxygen receives 2 electrons, so it has the electronic configuration like neon.
In scandium, the number of electrons in each energy level can be calculated using the formula 2n^2, where n is the principal quantum number representing the energy level. Scandium has 21 electrons, so it would have 2 electrons in the first energy level (n=1), 8 electrons in the second energy level (n=2), and 11 electrons in the third energy level (n=3).
