How many valence electrons are in PF,? 2. Draw the electron dot diagram is this molecule polar or nompolar? How many valence electrons are in CH,CP Draw the electrom dot diagram Is this molecule polar or nonpolar? 4. How many valence electrons are in CCl? Draw the electron dot diagram. Is this molecule polar or nonpolar? . In making the models, when do you use a stick and when do you use springs to represent a bond? 6. Give the charge (e g, 2t, 3-) of a polyatomic ion that has one less electron than the sum of its valence electrons 7. Give the charge of a polyatomic ion that has two more electrons than the sum of is valone eletrnons Instructor s Inirials Lab 7 85
