What is a weakness for gold?

The atomic number is 79. Gold does not react with most chemicals but is attacked by chlorine, fluorine, aqua regia and cyanide and dissolves in mercury. In particular, gold is insoluble in nitric acid, which will dissolve most other metals. Nitric acid has long been used to confirm the presence of gold in items.

Why is gold so 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.

Does gold get weak over time?

Gold is very tough, and will only break along a solder line, a place where the width is very thin, or a defective area of pitting (tiny air bubbles from a poor quality fabrication). Sadly, the very quality which makes gold submit to our design processes, also makes it subject to wearing down over the years.
