Web3 mrt. 2024 · Potassium is one of the alkali metals. All of the alkali metals have a single valence electron in the outer electron shell, which is easily removed to create an ion with a positive charge – a cation, which combines with anions to form salts. Naturally occurring potassium is composed of three isotope... WebTo illustrate Hund's rules using potassium (K), we can use its orbital notation: 1s2 2s2 2p6 3s2 3p6 4s1. The numbers indicate how many electrons there are in each orbital—in this case 2 in the 1s, 2 in the 2s, 6 in the two p-orbitals combined (3x2=6), etc.—and arrows above or below signify their spin (+1/2 for up arrow or -1/2 for down arrow).
