Term | Definition |
Atom | Smallest piece of matter that has the same properties of the element it is in. |
Proton | A positive + subatomic particle in the atoms nucleus. Is the identity of the element and the atomic number. |
Neutron | A neutral subatomic particle in the atoms nucleus... has no charge and most of the mass |
Electron | A negative subatomic particle spinning outside the nucleus of an atom. Tiny ! |
Element | The simplest forms of matter that contains only one type of atom. |
Periodic Table of Elements | A chart that organizes all the elements by atomic number and properties. |
Valence Electron | The electron in the outer level of an atom that causes atoms to bond together. |
Chemical Bond | An interaction that holds 2 atoms together. |
Chemical Bonding | The joining of atoms to form new substances |
Ionic Bond | Is formed when electrons are transferred from one atom to another |
Ion | Charged particle or atoms that gained or lost electrons |
Chrystal Lattice | Repeating 3 dimensional pattern that forms when Ions bond. |
Covalent Bond | The type of bond that forms when atoms share electrons instead of transferring. |
Metallic Bond | A special bond between metal ions and the electrons that swim around them |
Ductility | Metals can be stretched and drown into wires. |
Mallebility | Metals can be pounded into thin sheets. |
Electron Dot Diagram | An easy way to show the valence electrons in an atom or chemical bond. |
Compound | A set of elements that are chemically bonded and changed into new substances NaCl=salt |
Conductivity | Metals can conduct electricity and heat. |
Chemical Formula | A shorthand way to use chemical symbols and numbers to represent a substance. (H2O) |
Chemical Equation | Uses symbols to show the relationship between the reactants and the products C+O2 -> CO2 |
Subscript | (H2O)- small number to the right of the elements that shows how many atoms there are of the element. |
Coefficient | The large number that multiplies atoms of the element. 2Cl + 3Na |
Reactant | A substance or molecule that starts a chemical reaction. |
Product | The substance that forms as a result of a chemical reaction. |
Law of Conservation of Mass | States that matter is neither created nor destroyed in a chemical reaction |
Synthesis Reaction | When two or more substances combine to create one new compound |
Decomposition Reaction | A reaction where a single compound breaks down to form 2 simpler substances |
