All atoms have an atomic number. But what is the chemical element that has 57 as atomic number?
The answer is Lanthanum and there is so much cool stuff about Lanthanum that people don't know that I would keep reading if I were you.
Alright now to the facts!

Uses
It is used in the electodes of high-intensity, carbon-arc lights. Also used in the production of high-grade europium metal. Because it gives glass refractive properties, it is used in expensive camera lenses.
