| Question | Answer |
|---|---|
| What is the simplest collection of atoms from which an ionic compound's formula can be established? | Formula Units |
| Mixing of two of more atomic orbitals of similar energies on the same atom to give new orbitals of equal energy? | Hybridization |
| Which type of bond has the greatest bond energy? | Single Bond |
| Which type of bond has the shortest bond length? | Triple Bond |
| What is the small discrete unit of a covalently bonded atoms? | Molecule |
| What is a mutual electrical attraction between the nuclei and valence electrons of different atoms that binds the atoms together? | Chemical Bond |
| What electrons are involved in the formation of a chemical bond? | Valence Electrons |
| What is the electrostatic attraction between positively charged nuclei and negatively charged electrons that permits two atoms to be held together? | Chemical Bond |
| What is the bond of two covalently bonded atoms that are identical? | Nonpolar Covalent |
| Which bond has atoms that share electrons have an unequal attraction for the electrons? | Ionic |
| What are most chemical bonds? | Purely Ionic |
| What is a neutral group of atoms held together by covalent bonds? | Molecule |
| What group of elements satisfies the octet rule without forming compounds? | Noble Gases |
| What ions or bonding in molecules cannot be correctly represented by a single Lewis Dot structure? | Polyatomic |
| What are the mobile electrons surrounding the positive ions in a metallic bond? | Dipole |
| What foundation is the concept that electrostatic repulsion between electron pairs surrounding an atom causes these pairs to be separated as far as possible? | VSEPR Theory |
| What is the strength of inter molecular forces compared to molecular bonds? | Weaker |
| Attraction between cation(+) and anion(-) ; achieve a full valence shell, not a complete transfer of electrons | Ionic Bonds |
| Electrons are shared between two atoms, usually occurs in molecular compounds composed of nonmetals only | Covalent Bonds |
| Metal atoms share mobile "sea" of electrons, electrons move easily, conduct electricity | Metallic Bonds |
| Unbonded "Free" atoms have high Ep (potential energy); bonding causes decrease Ep, energy often given off | Energetics of Bonding |
| The amount of energy needed to break a bond | Bond Energy |
| "S" and "P" orbitals blend when bonding to form hybrid orbitals | Hybridization |
