Formulas Lesson 4: Transition Metals Part 2

The following episode looks at Naming Ionic Compounds when the metal contains more than one charge. We look at using both the Classical system and Stock system for naming such ionic compounds. Download this episode from iTunes by typing "PapaPodcasts" in the search window.

My chart says Mn is +2

[Papapodcasts]

@xXxBlackwaterXxX Mn also has a +4 charge. Transition metals typically have more than one possible charge.

i thought u said transitional metal were from 3-12 columns but u used lead...

[Papapodcasts]

@biggs95 Yes I did say that. Sure I used Pb but if I said that transition metals go all the way to Group 16, look at the atoms such as N, O, P, S, which are in this range and they are NOT transition metals. So i explain using groups 3-12 because they will not conflict with the non-metals that are after these metals.

So I'm at the part where it says lead can be +2 or +4... but what about +3, +5, etc? What determines what the elements can be, and how do we know? Is the roman numeral always equal to the charge?

[Papapodcasts]

@strawberry765 I sure hope your teacher provides you with a Periodic Table that will include the charges. I will send you a link to the Periodic Table I let my students use. Yes the Roman numeral represents the charge of the metal.

You are amazing. Where have you been all my life? With you I am feeling positive about chemistry.

[Bballgirly042]

Wow thank you so much I wish you were my teacher!

[abclol3kid]

Hey im confused i know how to work our the charges of the 7 groups because based on what group the metal or non metals are in u can work out the charge but transition metals are not given groups so how do u work out the charge for them?

[NadaNabulsi97]

if oxygen is -4 and u said it has to be -2 can i divide?

[XA5567]

I will be having my quiz tommorow, wish me luck! And aslo very very big THANK YOU! I had clearer view on naming and writing compounds.
