Term | Definition |
---|---|
Chemical Bonding | The joining of atoms to form new substances |
Ionic Bond | Formed when electrons are transferred from one atom to another atom |
Ion | Charged Particle or and atom that gained or lost electrons |
Crystal Lattice | repeating 3 dimensional pattern that forms when ions bond |
Covelent 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 |
Chemical Bond | an interaction that holds two atoms together |
Valence Electron | the electrons in the outer level of an atom that causes atoms to bond together |
Periodic Table of Elements | A chart that organizes all the elements by atomic number and properties |
Element | The simplest form of matter that only contain one kind of atom |
Electron | A negative subatomic particle spinning outside nucleus of an atom |
Neutron | A neutral subatomic particle in an atom's nucleus. It has no charge and is the most of the atom's mass |
Proton | A positive subatomic particle in the atom's nucleus. Identity of the element and atomic number. |
Atom | Smallest piece of matter that has the same properties of the element it is in. |
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. Example NaCl = salt |
Conductivity | Metals can conduct heat to cook food or electricity through wires |
Chemical Formula | A shorthand way to use chemical symbols and numbers to represent a substance |
Subscript | Small number to the right of the element to show how many atoms of the element |
Coefficient | The large number that multiplies atoms of that element |
Chemical Equation | Uses symbols to show the relationship between the reactions and the product |
Reactant | A substance that starts a chemical reaction |
Product | the substance that forms as a result of the chemical reaction |
Law of Conservation of mass | States that matter is neither created nor destroyed in a chemical reaction |
