| Question | Answer |
|---|---|
| Atom | Building blocks of matter made of protons neutrons and electrons. |
| Proton | Positive charge, found in nucleus. |
| Neutrons | No charge, found is nucleus |
| Electrons | Negative charge, found in energy level s around the nucleus. |
| Bohr Diagram | Energy levels of an atom, and shows all electrons |
| Lewis Structure | Shows valence atoms |
| Atomic Number | Protons + neutrons |
| Atomic mass | Protons or electrons |
| Energy level | Energy levels of an atom |
| Leptons | Electrons |
| Isotope | C-12,C-13,C-14 |
| Quark | Pin |
| Nucleus | Center of an atom |
| Valence | Electrons on the outer most shell |
| Family | Metals,nonmetals,metalloids |
| Chemical Symbol | Big letters that stands for the element |
| Metal | Part of the family and can be made into stuff |
| Nonmetal | Not a metal part of the family |
| Metalloid | A mixture between nonmetals and metals part of the family |
| Period | A name given to a horizontal row |
| periotic table | has all the elments |
| compound | two or more substances that are chemically combined |
| mixture | two or more substances that is not chemically combined |
| matter | anything that has mass |
| chemical property | something that undergoes a chemical change |
| chemical change | when two or more substances form into a new substance |
| pysical change | can be brought back to it's regular form |
| monomer | building blocks of complex molecules |
| polymer | plastics |
| petrochemical | a chemical made from crude oil |
| ion bond | bond that envolves a metal and nonmetal |
| ion | is an atom or molecule in which the total number of electrons is not equal to the total number of protons, giving the atom or molecule a net positive or negative electrical charge |
| covalent bond | a chemical bond that involves the sharing of electron pairs between atoms. |
| Reation Rate | The speed at which a chemical reaction takes place |
| conservation of mass | Law that states the total mass of the reactants must equal the total mass of the products |
| Oxidation number | a number assigned to an element in chemical combination that represents the number of electrons lost (or gained, if the number is negative) by an atom of that element in the compound. |
| chemical formula | a set of chemical symbols showing the elements present in a compound and their relative proportions, and in some cases the structure of the compound. |
| Chemical equation | A written representation of a chemical reaction, in which the symbols and amounts of the reactants are separated from those of the products by an equal sign, arrow, or a set of opposing arrows. |
| reactants | a substance that takes part in and undergoes change during a reaction. |
| products | The compounds that are formed when a reaction goes to completion |
