Explain the relationship between atoms, neutrons, protons, electrons, and molecules. Give examples using CO2 and H2O.

Molecules contain atoms, which contain a nucleus with protons and neutrons and circling electrons. In CO2, there is 1 carbon atom and 2 oxygen atoms. In H2O, there are 2 hydrogen atoms and 1 oxygen atom. These all contain certain a certain number of protons, neutrons, and electrons. The proton and electron number (which is the same) is on the top right corner of the periodic table and is also the atomic number. The number of neutrons is the atomic weight minus the atomic number.
