Yes. It has lots of stable isotopes.
Perhaps Ytterbium, which has 103 neutrons and 70 electrons.

it is found every where on earth
The strongest electromagnetic force on Earth is found between the North and the South Poles. The source of the force is found in the core of the Earth, which is rotating slightly faster than the Earth's own rotation, creating a generator of immense proportions.

Ytterbium is a naturally occuring rare earth element. However, an isotope of Ytterbium (Ytterbium-169) is an artificially produced isotope.
it is found on the moon
Ytterbium is obtained from other rare earth elements in several rare minerals, gadolinite, monazite and xenotime.
Jean de Marignac is the one credited with discovering the element ytterbium. He found this element in Switzerland in 1878.

Ytterbium, Yttrium, Terbium & Erbium are all named after the city, and it's mine, where the new elements were found; Ytterby Quarry, Ytterby, Sweden.
Ytterbium oxide is any oxide of ytterbium, but especially the colourless solid Yb2O3.
Yb is a rare-earth and a Lanthanide metal.
ytterbium man made
ytterbium has 70 protons.
Ytterbium's average atomic mass is 173.04.
Ytterbium is reactive (the Pauling scale index is 1,1).
