It is so hot because the sunshine is abundant.

The abundance of neodymium in the earths crust is approx. 40 ppm.

Beryllium concentration in the earth crust: 2,8 mg/kg

Beryllium concentration in the sea water: 5,6.10-6 mg/kg

Beryllium in the sun and solar system, as atom mole fraction relative to silicon+1:

4.10-7

The answer is unanswerable due to the fact that it is unknown. The total collection of all the gold that has been found on Earth would make a cube of 40 feet. If you know where to find more, feel free to leave me information in my message area.

The fractional abundance is calculated by dividing the abundance of the isotope of interest by the abundance of all the isotopes of the element. For chlorine-37, the percent abundance is 0.2434, or 24.34%.
