1s2 2s2 2p6 3s2 3p6
The electron configuration of 1s22s22p3s1 is not the ground state electron configuration of any element. This configuration contains 8 electrons, which in the ground state would be oxygen. The ground state configuration of oxygen is 1s22s22p4.
Cobalt electron configuration is [Ar]3d7.4s2.Cobalt(2+) electron configuration is [Ar]3d7.
Li, Be, O: the first term in the abridged electron configuration is [He]. Ca, K: the first term in the abridged electron configuration is [Ar].
The electron configuration for neutral Barium is [Xe] 6s2. Barium plus 2 means it has lost 2 electrons, so the electron configuration for Barium plus 2 would be [Xe].
There are four electrons in a Beryllium atom. Hence the mono positive ion has only three electrons. Therefore the electron configuration is 1s2 2s1.
The electron configuration for a magnesium cation Mg2 plus is 1s2.2s2.2p6.
When potassium achieves a noble gas electron configuration, it loses one electron to form the K+ ion. The K+ ion has a stable electron configuration similar to that of argon, with 18 electrons.
The Fe2 plus electron configuration is 1s2 2s2 2p6 3s2 3p6 3d6.
The ion formed when potassium achieves noble-gas electron configuration is K+ (potassium ion). This occurs when potassium loses one electron to have a full outer electron shell, similar to the nearest noble gas, argon.
The element with the electron configuration 2s1 is lithium (Li). However, there is no element with the electron configuration S2d1 as "S" and "d" are not valid subshells in the electron configuration notation based on the periodic table.
K+ is 18 electrons 1s2 2s2 2p6 3s2 3p6
The electron configuration for a potassium ion (K+) is [Ar] 4s1. Potassium loses one electron to form the +1 ion, resulting in a noble gas configuration like argon.
