Can you explain how and why? cular Models Pre-Lab Questions ) Lewis Structures are used to represent covalently bonded molecules and polyatomic ions. a. Answer the following to draw the Lewis Structure of the molecule of OF i. How many valence electrons (total) are you working with? ii. Which atom is the central atom? What criteria must you use to decide this? Do the atoms in the molecule all obey the octet rule? Are there any lone pairs on the...
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...
