| A | B |
|---|
| Atomic Number | Number of protons in the nucleus |
| Atomic Mass | Protons + Neutrons = ? |
| Malleable | Easily bendable; easily shaped |
| Atoms | Smallest particle into which an element can be divided and still have the properties of that element |
| Nonmetals | Conduct heat poorly, dull, low melting point |
| Most abundant element in the universe | hydrogen |
| The physical building block of all other elements | hydrogen |
| Birthplace of all elements | STARS! |
| Father of the Periodic Table | Dmitri Mendeleev |
| Law of Conservation of Mass | Matter is neither created nor destroyed. It merely changes forms. |
| electron | negatively charged particle found outsinde the nucleus |
| nucleus | Center of the atom. Contains protons and neutrons |
| proton | positively charged sub atomic particle in the nucleus |
| neutron | sub atomic particle in the nucleus with no charge |
| newtons (N) | Standard Unit for force is a newton. |
| Newton's Laws of Motion | 3 laws developed by Isaac Newton that explain the motion of objects |
| Newton's Law modeled in rocket launch lab | Newton's 3rd Law of Motion: For every action there is an equal but opposite reaction. |
| reactant | compound or element that changes during a chemical reaction |
| product | compound or element that is the result of a chemical reaction |
| element | made up of only one kind of atom |
| Periodic Table of Elements | a chart where all types of atoms are organized according to their properties |
| isotope | atoms of the same element with different numbers of neutrons in the nucleus, and thus different atomic masses. EX: carbon-12 and carbon-14 |
