Covenant Bonding

3. elements tend to bond in such a way that each atom has eight electrons in its valence shell
4. a large molecule made up of chains or rings of linked repeating subunits
7. one or more atoms of carbon are covalently linked to atoms of other elements
8. seven unique molecules that are composed of two atoms
11. two or more nonmetal atoms bond by sharing valence electrons
14. a model used to predict the geometry of molecules based on minimizing the electrostatic repulsion of a molecule's valence electrons around a central atom
17. a compound made up of two elements
21. chemical bond between two chemical elements involving four bonding electrons

1. diagrams that show the bonding between atoms of a molecule
2. a type of bond that occurs when two atoms share a pair of electrons with each other
5. a representation of a substance using symbols for its constituent elements
6. a chemical link between two atoms or ions in which the electron pairs are shared
9. a measure of how strongly atoms attract bonding electrons to themselves
10. ion composed of two or more atoms covalently bonded or of a metal complex that can be considered to be acting as a single unit
12. the amount of energy required to break apart a mole of molecules into its component atoms
13. a chemical bond between two atoms involving six bonding electrons
15. a chemical bond between two atoms involving two valence electrons
16. a pair of valence electrons that are not shared with another atom in a covalent bond
18. Any of several forces, especially the ionic bond, covalent bond, and metallic bond, by which atoms or ions are bound in a molecule or crystal.
19. covalent bond between two atoms where the electrons forming the bond are unequally distributed
20. a group of atoms bonded together, representing the smallest fundamental unit of a chemical compound that can take part in a chemical reaction
