How do scientists distinguish between an element and a compound? List two elements and two compounds.

Answer 21

Boron and Oxygen are the two elements
Water and Carbon Dioxide are the two compounds
and they distinguish between them by looking at the atoms that compose the substance they are observing and compare them to other atoms of the same substance and then they compare to the atoms of elements and they do this on multiple sections of the substance to back up their findings and they go by whether or not the atoms are all alike or have some different atoms in it and then if they have different atoms in it they compare the different atoms to those of different elements and figure out which ones it is composed of
