What is gold made of?
Gold is the chemical element with 79 protons in each atomic nucleus. Every atom containing 79 protons is a gold atom, and all gold atoms behave the same chemically. In principle, we can therefore create gold by simply assembling 79 protons (and enough neutrons to make the nucleus stable).
Why is gold rare?
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.
