How rare is gold in the universe?

Gold is rare throughout the Universe because it’s a relatively hefty atom, consisting of 79 protons and 118 neutrons. That makes it hard to produce, even in the incredible heat and pressure of the ‘chemical forges’ of supernovae, the deaths of giant stars responsible for creating most chemical elements.

What makes up 80% of air?

The air we breathe is almost 80% nitrogen and only 20% oxygen! Higher in the atmosphere the composition is different and there is the famous ozone layer which is very rich in oxygen.

Is there gold in the human body?
