| Term | Definition |
|---|---|
| Atom | building blocks of matter |
| proton | positive charge found in nucleus |
| neutron | neutral charge |
| valence | electrons on the last shell of an atom |
| atomic mass | number of protons and electrons |
| atomic number | number of protons and electrons |
| nucleus | center of atom holds protons and electrons |
| Bohr diagram (()) | shows all electrons |
| quark | makes up protons and electrons held together by gluons |
| chemical symbol | represents the chemical |
| energy level | the different rings. |
| electron | negative charge |
| Lewis structure | shows valence electrons |
| isotopes | c12 c13 c14 |
| lepton | makes up electrons |
| periodic table | the system used to show and order elements |
| period | the rows of the periodic table |
| group/family | the columns of the periodic table |
| metals | good conductors of heat and electricity, are malleable and ductile and even shiny |
| nonmetals | do not conduct heat or electricity |
| metalloids | have some properties of metals and nonmetals called a semiconductor |
| Compound | two or more substances chemically combined |
| Mixture | two or more substances not combined chemically |
| Matter | anything with mass or volume |
| chemical property | describes how a substance will react to another substance |
| physical property | used to describe the physical characteristics of matter such as shape or size |
| physical change | a change in size shape or state |
| chemical change | (chemical reaction) creates a new substance |
| monomers | molecules that are linked together to make a plymer |
| polymer | made of monomers such as DNA |
| petrochemicals | chemicals made of petroleum |
| Ion | atom that has lost or gained electrons |
| Ionic bond | the transfer of bonding metals or nonmetals |
| covalent bond | bond between two non metals that involves sharing |
| Chemical equation | what represents a chemical reaction |
| Reactants | substance that starts a reaction |
| product | 2MgO |
| oxidation number | hypothetical numbers assigned to an individual atom or ion |
| conservation of mass | states that for any system closed to all transfers of matter and energy (both of which have mass), the mass of the system must remain constant |
| chemical formula | The final product of a chemical reaction |
