Etymology
Sm is the chemical symbol for samarium, a grey metal named after the mineral samarskite, which was named for a Russian mining official called Samarsky. A helpful way to remember it is to think of the name 'Sam' attached to a metal, and the letters Sm are its short label on the periodic table as element 62.
