This week in class we learned about the chemical properties of atoms and how they chemically react to each other. This image shows the periodic table of elements. Elements are substances with only one type of atom not a combination of atoms to make compounds. Compounds have certain mixtures of atoms. Elements do not have compounds, they have molecules which unlike compounds have only one type of atom. Water is has compounds. One compound has multiple molecules.
Have you ever wondered what H2O Meant. The "H" stands for hydrogen. The "O" stand for oxygen. Finally the little "2" stands for the amount of hydrogen molecules. Since there is only one oxygen molecule there is no number for it. H2O, Water.
If you see an element it will only say N (nitrogen) or I (iodine).
