1. mutual electrical attraction between nuclei and valence electrons of different atoms is a(blank) bond
4. repulsion between the sets of valence-level electrons surrounding an atom causes these sets to be oriented as far apart as possible is (blank) theory
5. indicates the relative number of atoms of each kind in a chemical compound by using the atomic symbols and numeric subscripts is call a chemical (blank)
6. the percentage by mass of each element in a compound
8. the chemical bonding that results from the attraction between metal atoms and the surrounding sea of electrons
10. a chemical compound whose simplest units are molecules is called a molecular (blank)
14. the ability of a substance to be drawn, pulled, or extruded through a small opening to produce a wire
15. a number assigned to an element in chemical combination which represents the number of electrons lost or gained, if the number is negative, by an atom of that element in the compound
16. bonding in molecules or ions that cannot be correctly represented by a single Lewis structure
18. a neutral group of atoms that are held together by covalent bonds
19. ions formed from a single atom are

2. the mixing of two or more atomic orbitals of similar energies on the same atom to produce hybrid atomic orbitals of similar energies
3. bonding that results from sharing electron pairs between two atoms
7. the ability of a substance to be hammered or beaten into thin sheets
9. a charged group of covalently bonded atoms is a (blank) ion
11. the energy released when one mole of an ionic crystalline compound is formed from gaseous ions is called (blank) energy
12. created by equal but opposite charges that are separated by short distance
13. a bond with an uneven distribution of charge
17. chemical bonding that results from electrical attractions between cations and anions is (blank) bonding
