mixture
Gold itself is an element. All of the gold you are likely to see (rings, watches, plating, etc.) is an alloy (mixture) of gold and other metals. Even "pure gold" jewellery (24 k) is only +99.9% pure
Sand on the beach is a mixture of compounds. Pure sand is white and its chemical name is Silicon Dioxide (SiO2)' a compound. The red brown colour comes from iron(III) salts mixed in ther sand. The Iron(III) saltsd will also be a mixture of compounds.

It is a compound. not an element. Element #101 is not plastic, but Mendelevium, Md, a radioactive and rare Earth metal named after the founder of the Periodic Table, Dmitri Mendeleev. It has a silvery white or grey appearance due to it's metallic structure. It's Chemical Obstruct Service Registry # is 7440-11. Mendelevium is definitely not plastic. Which makes plastic a compound made of carbon, hydrogen, and oxygen.
