The atomic number of a chemical element is the number of protons found in the nucleus of the atom of that element.Ok so I'll take you through some interesting facts and data about Lanthanum (That most people don't know).
Lanthanum Overview
Atomic Symbol
La (Lanthanum)
Description
Soft, silvery-white, malleable, ductile metal.
State at 20 °C
Solid
Sources
Found with rare earths in monazite and bastnasite. Monazite sand typicall contains 25% lanthanum.

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.
