A pure substance made of only one kind of atom, can not be broken down
A substance made up of atoms of two or more different elements joined by chemical bonds
each of two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei, and hence differ in relative atomic mass but not in chemical properties; in particular, a radioactive form of an element.

A substance that is dissolved in a solution.
the substance in which the solute dissolves
scale with values from 0 to 14, used to measure the concentration of H+ ions in a solution; a pH of 0 to 7 is acidic, a pH of 7 is neutral, and a pH of 7 to 14 is basic
