chemistry
| Term | Definition |
|---|---|
| Atom | Smallest piece of matter that has the same properties of the element it's in. |
| Proton | A positive subatomic particle in the atom's nucleus. Its the identity of the element and atomic number. |
| Neutron | A neutral subatomic particle in the atoms nucleus...has no charge and most of the mass |
| Eletron | A negative subatomic particle spinning outside the nucleus of an atom. Tiny! |
| Element | The simplest forms of matter hat contain 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 atom 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 on atom to another |
| Ion | changed particle or atom that gained or lost electrons |
| Crystal 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 them |
| Metallic bond | A special bond between metal ions and the electrons that swim around them |
| Malleability | metals can be pounded into thin sheets |
| Ductility | Metals can be stretched and drawn into wires |
| Electron dot diagram | An easy way to show the valence electrons in an atom or chemical bonds |
| Compound | A set of elements that are chemically bonded and changed into new substances NaCL=Salt |
| Electrical conductivity | Metal can conduct or carry electricity through wires |
| Thermal Conductivity | Metal can conduct or carry heat in order to cook food |
| Chemical formula | a shorthand way to use chemical symbols and numbers to represent a asubstance |
| Chemical Equation | Uses symbols to show the relationship between the reactants and the products |
| Subscript | small number to the right of the element that shows how many atoms there are of the element |
| Coefficient | the large number that multiplies the atoms of the element |
| Reactant | A substance or molecule that starts a chemical reaction |
| Product | The substance that forms as a result as a chemical reaction |
| Law of Conservation of mass | States that matter is neither created nor destroyed in a chemical reaction |
| Synthesis Reation | when two or more substances combine to create one new compound |
| Decomposition reaction | a reaction where a simple compound breaks down to form 2 simpler substances |
| Single displacement | one element replaces another element in a compound leaving a new compound and one element |
| Double displacement reaction | the two metal ions in 2 compounds with places in chemical reaction |
| indicator | will change colors in the presence of an acid or base |
