Potassium is the group 1, period 4 element on the periodic table. That means that its electron configuration is 1s2 2s2 2p6 3s2 3p6 4s1. This can be shortened to [Ar] 4s1 because argon's electron configuration is 1s2 2s2 2p6 3s2 3p6.
The element aluminum (atomic number 13) has the electron configuration [Ne] 3s2 3p1 which is completely expressed by 1s2 2s2 2p6 3s2 3p1
Definition: A noble gas core is an abbreviation in an atom's electron configuration where the previous noble gas's electron configuration is replaced with the noble gas's element symbol in brackets. ... This is the noble gas core notation of sodium.
A unit of matter, the smallest unit of an element, having all the characteristics of that element and consisting of a dense, central, positively charged nucleus surrounded by a system of electrons. The entire structure has an approximate diameter of 10 -8 centimeter and characteristically remains undivided in chemical reactions except for limited removal, transfer, or exchange of certain electrons.
