The Full Set

All 118 elements, one card each. Pull any of them from the table: turn the sample in your hand, then flip to its atom and change the isotope. The rarity on each card is how much of it there is in the Earth's crust.

Alkali metals

Soft, silvery and so eager to lose their one outer electron that they fizz in water.

3LiLithium11NaSodium19KPotassium37RbRubidium55CsCesium87FrFrancium

Alkaline earth metals

Two outer electrons, a little calmer than the alkalis; the stuff of bones, shells and fireworks.

Transition metals

The broad middle of the table: hard, shiny, often coloured, the metals of tools and coins.

Post-transition metals

Softer metals with low melting points, from aluminium foil to tin and lead.

Metalloids

Half metal, half not. Silicon and germanium made the electronics age.

Reactive nonmetals

Hydrogen, carbon, nitrogen, oxygen, phosphorus, sulfur, selenium: most of what living things are made of.

Halogens

One electron short of a full shell and hungry for it; they make salts with metals.

Noble gases

Full outer shells, so they barely react. Pass a current through them and they glow.

Lanthanides

The rare earths: strong magnets, phone screens and lasers.

Actinides

All radioactive. Uranium and thorium occur in nature; most of the rest are made in reactors.

101. Mendelevium (Md)

Built one atom at a time. In 1955 Berkeley fired alpha particles at about a billion einsteinium atoms and caught 17 atoms of a new element. Seaborg needed US government approval to name it, at the height of the Cold War, after the Russian Dmitri Mendeleev.
