electron configuration for k+1

As we learned earlier, each neutral atom has a number of electrons equal to its number of protons. To obtain a +1 charge it loses an electron, resulting in a configuration of [Ar]. To form K+1we remove electron. Therefore, the number of electrons in an atom of an element is equal to the element's atomic number (Z): But the atomic number (Z) only tells us how many electrons in total there are around the nucleus of a neutral atom, it doesn't directly tell us how those electrons are arranged around the nucleus. Indeed, we find that the K shell can contain a maximum of only 2 electrons, but the next shell, the L shell, can contain a maximum of 8 electrons. To form K + 1 we remove electron. The electronic configuration of K is 1 s 2 2 s 2 2 p 6 3 s 2 3 p 6 4 s 1.
