All the magic that we know is in the transfer of electrons. Reduction (gaining electrons) and oxidation (the loss of electrons) combine to form Redox chemistry, which contains the majority of chemical reactions. As electrons jump from atom to atom, they carry energy with them, and that transfer of energy is what makes all life on earth possible.

I got even more confused thanks to that marriage analogy
I love watching Crash course on 2x speed.
oh my goodness
is that President Trump? LOL
Am I the only one thinking that the guy surrounded by the gold coins looks like Donald Trump??
I feel like Crashcourse doesn't actually help that much. It sometimes goes too deep and makes it more confusing.
I always thought it's called "reduction" because in reduction the oxidation number decrease

"wake up students! The bell went…"
Where did the sudden hydroxide ion come from? 9:05 you did not mention it at all before in the video and then it just showed up for what reason?
Who else is lost?
i think chemistry is magic for all about happening around yes i can see oxidation and reduction in front of me like molecules residing on the laptop do this stuff
Chicken
Need so much more details. Just telling me things do things with near no explanation, this is killin me bruh ;.;
U are not bad at delivering but nobody could ever match Mr Tyler Dewitt. He is a gifted teacher
Thank God now the speed of your lecture is better. Otherwise i found it too difficult to catch up whatever u said
I know this video is old, but the typos are making it really hard to understand :/ like at 9:37, the oxidation numbers on Silver are wrong. They should be switched with the reactant as +1 and the product as +/-0
nice explain ..
Was that Trump at 0:07?
He sounds like the scientist in Spy Kids tho
10:05 he got pure silver

Rule one
Atoms, by definition, do not have a charge. If they had a charge they would be ions. And if they’re sharing with themselves, they share it[electrons] equally.
Rule two
For a monatomic ion, basically a charged atom, it’s simply the size or number of its charge.
Example: So the iron (II) in Fe2+ has an oxidation state of plus two, while the chloride ion is minus one.
Rule three
Oxygen almost always has an oxidation state of negative two, unless it happens to be in a peroxide molecule like hydrogen peroxide.
Rule four
Hydrogen is plus one.
Rule five
Fluorine is negative one.
Why does he look like captain America
You can explain something in 10min something which needs usually a lot of time. I understood thermodynamic laws thanks to you. Which I haven't got for years.
Shouldn’t Ag have a reduction state of 0 after being reduced?
lets hope i pass my chem final
i remember reduction as the charge is being reduced(not really but it's negative because it has more electrons)
If you go to the beginning and keep hitting the left arrow, Hank would be singing the HEYAHEYAHEYA song from He-man LOL
that Donald Trump at the beginning made me lost it
taking the SAT chem subject test wish me luck :/
My chemistry teacher uses "LEO says GER" to memorize redox changes. "Loss of Electrons is Oxidation" and "Gain of Electrons is Reduction."
Would you mind reviewing Paraquat redox?
acid/base reactions don't include electrons? tell that to Lewis!!!!
If you can follow this guy you don't need to watch his videos. All he ever does is talk as fast as he can with no concern whatsoever if the student learns anything. If there were no students in his classroom he would still deliver the class to the wall because he just likes talking. Oh wait he's not a teacher.

0:03 is that Donald Trump?
That Tollens reagent reaction was nicely done especially that silver mirror I can’t even get that nice silver coating when I did the experiment
The way that I remember reduction is that the charge decreases because of the increase of electrons.
trump. lol
This is not actually how to get most people to really understand what's going on. This is a bullet list of classroom charts in case you're taking notes, but fails to connect with the real world. Not fun or revelatory to watch.
IF Ag was reduced in your half reaction example towards the end of the video. It would go from 1+ to 0. Correct? I still noticed it displayed as 1+ in the products in the video
Oilrig.
im sorry but did i just see donald at 0:03–0:08 wtf gtfo of my chemistry video don
chem test soon
good explanation but why does he have to talk like such a prick
shout out to every one thats here cramming for the AP chem exam tomorrow
How else zoned out for a minute and then didn't understand anything
I’m failing science guys!
