*The narrator draws the pairs of electrons in the first energy ring right next to each other. This is different from what we discussed, but is also correct.
*The narrator also takes the mass number from the PT. The mass numbers you will use will be in the name of the element you are drawing. For example, Carbon-14 has a mass of 14 (even though this is different from what the periodic table says).

**Note that both resources above include polyatomic ions that are written differently and/or not present on your periodic table. This should be taken into consideration when quizzing yourself. Quizzes/exams will only include the ones on your periodic table.
Common Inconsistencies:
- Acetate C2H3O2 1- charge This is different from the one on your PT.
- Phosphite PO3 3- charge This is absent from your PT.
- Silicate SiO3 2- charge This is absent from your PT.
