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 |
