The molecular formula
A compound naturally occurs when its constituent elements combine in specific ratios and bond together through chemical reactions. These reactions can take place in various natural processes such as volcanic activities, biological processes, or geological formations. The compound is then found in its natural state, either as a solid, liquid, or gas, in the environment.
Halogens occurs naturally as salts; an exception is HCl from volcanoes.

Only one of these occurs naturally.
the answer is that it occurs as a compound, not an element

Nitrogen naturally occurs as a diatomic molecule (N2). Nitrogen, by itself, is an element.
Most naturally occurring sand is a mixture, but some especially pure sand is a compound named silicon dioxide. This compound occurs in all other forms of sand.
I think one of the physical process that occurs naturally is blinking.
Fluorine is an element. It occurs naturally.
Chlorine is an elemental gas, but is technically a compound in its naturally occurring state because, like many gases, it occurs as CL2, rather than Cl. It can be part of a mixture if it is in solution with other gases or liquids.
Creatine is a naturally occurring compound derived from amino acids.
Yes, it occurs naturally on earth.
