It has been found that there are a few errors on the slides. Please check and revise them. On slide #28 Q13. How many valence electrons does nitrogen have? The answer says: D:7 → This must be “5”, not “7”. On slide #112 Q49. What is the EDG of CO2? The answer says: “B” → The right answer should be “A: linear”. On slide #140 Non-polar : very small or zero (→Less than 0.4 or zero) Polar: 0.2 to 1.6 →(This must be greater than 0.4 and less than 1.7) Ionic: above 1.7 → This would be fine.

Slide 82 on the Common Ions of Transition Metals has significant mismatches between the ion symbol and the ion name.
