Video 7-8.1: Naming Ion Notes
Answer these questions while watching the video:
1. Why do atoms form ions? (this is a question you’ve seen before and should be review!)
2. Create a rule for naming cations. Write it here:
3. Create a rule for naming anions. Write it here:
Answer these questions after watching the video:
4. For the transition metals, the charge of the ion is given by the Roman Numeral in its name. Remember,
these metals can have multiple charges so you must be told what the charge is on a case by case basis!
Since transition metals are metals, they follow the same rule as the cations above!
I-1
II - 2
III - 3
IV - 4
V-5
VI - 6
VII - 7
VIII - 8
IX - 9
X – 10
