Term | Definition |
---|---|
Electron Dot Diagram | diagrams that show the bonding between atoms of a molecule and the lone pairs of electrons that may exist in the molecule |
Ion | an electrically charged atom or group of atoms, the electrical charge of which results when a neutral atom or group of atoms loses or gains one or more electrons during chemical reactions, by the action of certain forms of radiant energy |
Anion | a negatively charged ion |
Cation | a positively charged ion |
Chemical Bond | an attraction between atoms that allows the formation of chemical substances that contain two or more atoms |
Ionic Bond | a chemical bond in which one atom loses an electron to form a positive ion and the other atom gains an electron to form a negative ion |
Chemical Formula | a representation of a substance using symbols for its constituent elements |
Crystals | solids whose particles are arranged in a lattice structure |
Covalent Bond | a chemical bond that involves sharing a pair of electrons between atoms in a molecule |
Molecule | a group of atoms bonded together, representing the smallest fundamental unit of a chemical compound that can take part in a chemical reaction |
Polar Covalent Bond | a type of covalent bond between two atoms in which electrons are shared unequally |
Polyatomic Ion | a charged chemical species composed of two or more atoms covalently bonded or of a metal complex that can be considered to be acting as a single unit |
Metallic Bond | a chemical bond in which electrons are shared over many nuclei and electronic conduction occurs |
Alloy | a metal made by combining two or more metallic elements, esp. to give greater strength or resistance to corrosion |
