PART C: LEWIS DOT STRUCTURES Use the Lewis Dot structure rules on page 92 of this lab manual for the following: Write Lewis electron dot structures for each of these diatomic gases: valence electron 2(I 2 valence efectron-215)-10 H, N, valence clecton valence electron Covalent compounds (these are not charged chemical species): a (4098 valence electron # valence electron So CH, valence electron # valence electron : so, SO O, (not a cyelic molecule) valence clectron valence electron .: PCI,...
Which of the following statements about Lewis Dot Structures is false? A. An octet is when an atom shares 8 valence electrons B. An ionic bond occurs when electrons are transferred C. A covalent bond occurs when electrons are shared D. A duet is a stable electron configuration for helium E. All the above statements are true
1. For each compound, draw the Lewis dot structure, the number of lone pairs, and the number of electronic groups for the central atom. Each Lewis dot structure follows the octet rule: hydrogen has one bond, all other atoms are surrounded by a total of eight electrons. Each covalent bond counts as we clectrons. Each nonbonded pair of electrons (lone pairs) count as two electrons. The number of nonbonded electrons is how many electrons from the central atom are not...
