Across
- 2. a single covalent bond that is formed when an electron pair is shared by the direct overlap of bonding orbitals
- 8. useful molecular model which uses letter symbols and bonds to show relative positions of atoms
- 9. occurs when a greater amount of energy is required to break the existing bonds in reactants than is released when the new bonds form in the product molecules
- 10. an acid that contains both a hydrogen atom and an oxyanion
- 12. chemical bond that results from equal sharing of electrons
- 13. Valence shell electron pair repulsion model
- 14. atomic orbitals are mixed to form new, identical hybrid orbitals
Down
- 1. forms when one atom donates a pair of electrons to be shared with an atom or ion that needs two electrons to become stable
- 3. that uses electron dot structures to show how electrons are arranged in molecules
- 4. occurs when more energy is released during product bond formation than is required to break bonds in the initial reactants
- 5. when more than one valid Lewis structure exists for the same molecule
- 6. when to or more atoms bond covalently
- 7. a bond that is formed when parallels orbitals overlap to share electrons
- 11. a type of bond that forms when electrons are not equally shared
