The calculation is beyond the IB. You would have to know more about the non-Mn part. Carbon can have variable oxidation states even within a compound - so this make the maths impossible. I added it for completeness.
This is somewhat beyond the IB. Normally 2 electrons can fall off of period 4 transition metals. More can also fall off with the addition of only a LITTLE more energy. Normally ionising more than the fixed number (1 in group 1, 2 in group 2 etc), requires a LOT more energy.
This is shorthand notation. Instead of writing out 2:8:8 or 1s2 2s2 2p6 3s2 3p6, this can be replaced by the nearest, lighter noble gas, in this case argon, [Ar]

At 01:45 you say that Mn has a charge of +1 in the compound MnC5H4CH3(CO)3
How did you calculate that? I tried and kept getting Mn as 5+
"Lazy bet you didn't pause" LOL how did you know?
I know it is quite off topic but do anyone know a good website to stream new movies online?
@Everett Rory i would suggest FlixZone. Just search on google for it :)
@Vance Leon yea, been using FlixZone for years myself :)
@Vance Leon thanks, signed up and it seems to work :) I really appreciate it !
@Everett Rory you are welcome :)
Thank you for this amazing straight to the point video
Why is it important to determine how many oxidation states an element has; what conclusions does it tell?
Totally not me the night before an exam
how do you do the oxidation state of Mn for MnC5H4CH3(CO)3? at 01:43

@@ibchemvids can you please tell me what the topic that includes learning the calculations is?
@@yousefahmad538 it's not in ib
@@ibchemvids thank you! I just spent 40 minutes trying to figure it out before I saw this ... :(
how much Valence Electrons have groups (families) 8, 9, and 10?

How does sc have 3+ oxidation number
the ionisation energies for 3d and 4s are similar and so Sc is able to exist in a 3+ state. Not sure about 2+ tho
so hlpful thankuu so mch
Very helpful
great vid, didn't make me sleep at all! ;-)
Thank u sir
Thanks...but it didnt let me to fall asleep😂
what does [Ar] means??
This is shorthand notation. Instead of writing out 2:8:8 or 1s2 2s2 2p6 3s2 3p6, this can be replaced by the nearest, lighter noble gas, in this case argon, [Ar]
copper with 3d9 makes me cringe internaly
3:37 LOL
thnx a lot
Do you by any chance play CS?
nope - I spawn and get immediately sniped through a gap 1 pixel wide!
I am so early that trump is majking good decision s
