For example, sodium (atomic number 11) has its 11 electrons distributed in the first three shells as follows: the K and L shells are completely filled, with 2 and 8 electrons respectively, while the M shell is only partially filled An electron configuration table is a type of code that describes how many electrons are in each energy level of an atom and how the electrons are arranged within each energy level. 4p6. ) 1. These names, together with the value of n, are used to describe the electron configurations of atoms. Scandium (Sc) is only 3 spots away with 21 electrons, but it has a configuration of 2-8-9-2. So whatever noble gas it's nearest to, we just figure out how many electrons we need to gain or lose to get there, and that'll be the charge. 60 The alkali metal electron configurations (group 1) always end with “s 1 ” and the alkaline earth metals (group 2) always end with “s 2 ”. Silicon has an electron configuration of 1s2 2s2 2p6 3s2 3p2. The element is much more stable and has a lower energy when the 4d orbital is filled, so one electron is placed there, rather than in the 5s orbital. What you see here is sort of a cross The ground state configuration for oxygen, for instance, can be written as : This means that the lowest energy configuration of oxygen, with 8 electrons, is to have two electrons in the n=1 s-subshell, two in the n=2 s-subshell, and four in the n=2 p-subshell. Sulfur's has an atomic number equal to 16, which means that a neutral sulfur atom has a total of 16 electrons surrounding its nucleus. N2^2+ shows 2 electrons less, i.
