They are all elements
Explanation:
1) INORGANIC COMPOUNDS ARE COMPOUNDS THAT ARE NOT MADE UP OF CARBON AND HYDROGEN.
2) They are also not made from living organisms, it's rather organic compounds that are made from living things
3) And for the 1st one, EVERYTHING! is made up of atoms because that is smallest unit or basic unit of matter
4) And so far all the inorganic compounds I've seen are elements, and that is the only valid answer.
