The reddish metal that carries electricity better than anything except silver, and which humans have been smelting…
Graphite
Pure carbon in soft, slippery sheets — the same stuff as pencil lead — and the material that holds the lithium when a…
Indium
A soft metal whose oxide is both transparent and electrically conductive — the invisible wiring on top of every…
Lithium
A soft, silvery metal so light it floats on water, and the element that lets a rechargeable battery store a lot of…
Neodymium
The rare earth at the heart of the strongest magnet ever made — the kind in headphones, hard drives, wind turbines…
