5. This is a collection of every known element. It gives each element a number and sorts them based on type (metals, metaloids, etc.)
8. This law states that all chemical compounds are made up of the same atoms in the same ratios, regardless of the size of the sample.
9. These are positively charged subatomic particles. These are found, along with neutrons, in an atom's nucleus.
11. These liquids produce hydrogen ions in aqueous solutions (Arrhenius model) and are proton donors (Bronsted-Lowry Model).
12. These are the tiny particles that make up everything. They are made of a positively charged nucleus and a negatively charged electron "cloud." There are many models of these particles, including the Bohr model and the chocolate chip cookie model.
13. This law states that matter can be neither created nor destroyed in a chemical reaction. It is shown when balancing a chemical equation.

1. This is the most abundant element in the universe. It is Element No. 1 on the Periodic Table
2. This describes the position of electrons in an atom's or molecule's orbitals. For example, 1s2 2s2 2p6 is the representation of Neon.
3. This law states that equal volumes of all gases, at the same temperature and pressure, contain the same number of molecules. Also known as Avocado's Law.
4. These things are pure substances made of atoms with the same number of protons. Hydrogen and Oxygen are two of these things.
6. This is the energy released from the decay of unstable nuclei. This energy was displayed in the Chornobyl disaster.
7. These are negatively charged subatomic particles. They orbit an atom's nucleus.
10. These liquids produce hydroxide ions in aqueous solutions (Arrhenius model) and are proton acceptors (Bronsted-Lowry model).
14. These are subatomic particles with no charge. They are found, along with protons, in an atom's nucleus.
