Ionic Bond | 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, three dimensional pattern that forms when Ions bond. |
Covalent 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. |
