Term | Definition |
Atom | This is the Smallest piece of matter that has the same properties of the element it is in. |
Proton | This is a Positive (+) subatomic particle in atoms nucleus. This is the identity of the element and atomic number. |
Neutron | This is a Neutral subatomic particle from the atoms nucleus. It has no charge and most of its mass. |
Electron | This is a Negative (-) subatomic particle spinning outside the nucleus of an atom. Tiny! |
Element | This is the Simplest form of matter that contain only one type of atom. |
Periodic Table of Elements | This is a Chart that organizes all elements by atomic number and properties. |
Valence Electron | This is the Electron in the outer level of an atom that causes atoms to band together. |
Chemical Bond | A 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 one atom to another. |
Ion | Charged particle or atom that gained or lost electrons. |
Crystal Lattice | Repeating 3 dimensional patterns that forms when ions bond. |
Covalent Bond | The type of bond that forms when atoms share electrons instead of transferring. |
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. |
Conductivity | Electrical-metal can conduct or carry electricity through wires, Thermal-metal can conduct or carry heat in order too cook food. |
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 & changed into new substances. |
Synthesis Reaction | When two or more substances Combine to create one new compound. |
Law of Conservation of Mass | States that matte is neither created nor destroyed in a chemical reaction. |
Decomposition Reaction | Reaction where a single compound breaks down to form 2 simpler substances. |
Single Displacement reaction | 1 element replace another element in a compound and 1 element |
Double Displacmet | 2 metal ions in 2 compounds switch places in chemical reactions |
Indicator | Will change colors in the presence of an acid or a base |
