Term | Definition |
---|---|
Atom | Smallest piece of matter that has the same properties of the elemental it is in. |
Proton | A positive subatomic particle in the atoms nucleus.Its the identity of the element and atomic and atomic number. |
Neutron | A nuetral 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! |
Elemental | The simplest forms of matter that 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 and together |
Chemical Bond | An interaction that holds 2 atoms together. |
Chemical Bonding | The joining of atoms to form new substances. |
ionic Bonding | Is formed when electrons are transferred from one atom to another atom. |
Ion | Charged particle or atom that gained or lost electrons |
Crystal Lattice | Repeating, 3 dimensional pattern that forms Ions bond. |
Covalent Bond | The type of bonds hat from when atoms share electrons instead of transferring them. |
Metallic Bond | A special bond between 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 |
Conductivity Electrical | Metals can conduct or carry electricity through wires. |
Conductivity Thermal | Metal can conduct or carry heat in order to cook food. |
Electron Dot Diagram | An easy way to show the valence electron in an atom or chemical bond |
Compound | A set of elements that care chemically bonded and changed into new substances NaCl=Salt. |
Chemical Formula | A shorthand way to use chemical symbols and numbers to represent a substance. |
Coefficient | The large number that multiplies atom of the element. |
Chemical Equation | Uses symbols to show the relationship between the reactions and the products. |
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 | State 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 simpler substances. |
Single Displacement Reaction | One element replaces another element in a compound leaving a new compound and 1 element. |
Double Displacement Reaction | The 2 metal ions in 2 compound switch places in a chemical reactions. |
Indicator | Will changes colors in the presence of an acid or a base. |
