Unformatted text preview: 2 O. | v v Solution Appendix B shows that the electron configuration for Li is 1s2 2s1 and for O it is 1s22s22p4. Thus, Li has one valence electron and is electropositive. Oxygen has six valence electrons and is electronegative. Li can obtain a filled valence shell by transferring its lone valence electron to the electronegative O atom. This results in the formation of a Li ion and an O ion. The O ion, however, still does not contain a filled valence shell. If a second Li atom transfers its lone valence electron to the O ion, the result is a stable group of ions composed of two Li and one O2 ( i.e., Li2 O). | e-Text Main Menu | Textbook Table of Contents 34 v v pg034 [V] G2 long-range order is established within the struct congruent melting The equilibrium melting reaction Curie temperature The temperature above w that occurs when a solid phase transforms to a liquid 7-27060 / IRWIN / Schaffer pgm 1-14-98 plm 3-21-98 MP ferromagnetic material exhibits paramagnetic phase having identical composition. characteristics. coordination number The number of nearest Czochralski method A process by which a s neighbors that surround an atom or ion.
