Chemistry
| Term | Definition |
|---|---|
| Atom | Smallest piece of matter that has the same properties of the element its in |
| Proton | The positive subatomic particle in the atoms nucleus is the identity of the element and subatomic number |
| Neutron | A neutral subatomic particle in the atoms nucleus has no charge and most of the mass |
| Electron | The negative sub atomic particle spinning around the nucleus and is tiny |
| Element | the simplest form of matter that contain only one type of atom |
| Periodic Table of Elements | A chart that organizes all of 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 two atoms together |
| Chemical Bonding | The joining of atoms to form new substances |
| Ionic Bond | is Formed when atoms transfer their electrons from one atom to another |
| Ion | Charge of particle or atom that gained of lost an electron |
| Crystal Lattice | A repeating 3 dimension pattern that forms an Ions bond |
| Covalent Bond | The type of bond when atoms share electrons instead of transferring them |
| Malleability | Metal can be pounded into thin sheets |
| Ductility | Metal can be stretched into thin metals |
| conductivity (electrical) | Metal can conduct and carry electricity through wires |
| Conductivity (thermal) | Metal can conduct or carry heat in or cook food |
| Electron Don Diagram | An easy way to show the valence electrons in an aton or chemical bond |
| Compound | A set of elements that are chemically bonded and changed into new substances |
| Chemical formula | a shorthand way to use chemical symbols and numbers to represent a substance |
| Chemical equation | uses chemical symbols to show the relationship between the reactants and the product |
| Subscript | small number to the right of the element that shows how many atoms there are of an element |
| Coefficient | the large number that multiplies atoms of the element |
| Reactent | The substance or molecule that starts a chemical reaction |
| Product | the substance that forms as a result of chemical reaction |
| Law of Conservation of Mass | Matter is neither created nor destroyed in a chemical reaction |
