Mendeleev Monday - Atomic Number 28 - Nickel (Ni). Nickel is one of three elements - the others being iron and cobalt - that are naturally (ferro)magnetic at room temperature. About two-thirds of all nickel goes into making stainless steel which is, in turn, used for cutlery, kitchen sinks, and many home appliances. Nickel is also used for the creation of electric vehicle batteries.
