Due Date: 2/23/07 Assignment #4 Chemistry 106 Chapter 5: Applying Your Knowledge 6) The octet rule says that in forming bonds, main group elements gain, lose, or share electrons to achieve a stable electron configuration with eight valence electrons. 8. No. Since calcium only has two electrons in its valence shell, it cannot have a charge of +3 naturally. 16. An ionic bond is based on the attraction between positive and negative ions. In covalent bonds, electrons are shared. 18.

Unformatted text preview: octet rule. This is because the octet rule requires the elements in the compound to each have a valence of eight after the bond is formed. Because of this, there is no way that a compound with an odd number of valence electrons can conform to the octet rule. 32. (c) gas 34. (a) liquid 40. (a), (b), (f), and (g) display hydrogen bonding because they have a hydrogen atom bonded to a highly electronegative atom (O, N, F) and the lone pair on an electronegative atom in another or the same molecule.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
