What are some examples of elements, atoms,compounds, mixtures, and molecule.
Thank you for helping me on this question
This is such a broad question.
Look on the periodic chart and pick out any of the 100+ elements. An atom is ONE of any given element, and some element combine with themselves to make molecules (H2, O2, N2 are example). Compounds are combination of elements, H2O is an example of a compound). Air is a mixture of gases, primarily nitrogen and oxygen (with about 1% Ar) plus minor amount of other gases.
