Across
- 8. the relative ability of an atom to attract electrons in a chemical bond
- 9. type of bond where the electrostatic force that holds oppositely charged particles together in an ionic compound
- 10. forms when parallel orbitals overlap and share electrons
- 11. type of reaction when more energy is released during product bond formation than is required to break bonds in the reactants.
- 13. type of bond that results from sharing valence electrons
- 14. region around an atom's nucleus that defines an electron's probable location
- 16. type of reaction that occurs when a greater amount of energy is required to break the existing products
- 19. the force that holds two atoms together
Down
- 1. one of the most useful molecular models
- 2. type of covalent bond that forms when one atom donates both the electrons to be shared with an atom or ion that needs two electrons
- 3. an acid that contains both a hydrogen atom and oxyanion
- 4. single covalent bonds
- 5. model used to determine the molecular shape
- 6. they can represent the arrangement of electrons in a molecule
- 7. process in which atomic orbitals mix and form new, identical hybrid orbitals
- 12. condition that occurs when more than one valid Lewis structure can be written for a molecule or ion.
- 15. a polyatomic ion in which an element is bonded to one or more oxygen atoms
- 17. when two or more atoms bond together covalently
- 18. unequal sharing results in this type of bond
