@@dominoscustomersupport4373 You have just to remember a strict mathematical rule. LOSS is Less or more negative.The trades are made in chemistry with electrons, particles that are negatively charged. So gaining electrons means becoming MORE negative that is in fact LESS.(-4 is less than -3 mathematically (-4 is a smaller number).

It's a bit sad that a video from 6 years ago helps me more than my current instructor.

Your explanation for determining the oxidized and reduced substances and oxidizing agent and reducing agent using concepts of electronegativity and oxidation state was on point. I also liked the whole color scheme that you used to explain the audience. Using Black background which is easy on the eyes, and different colors to represent different atoms/charges is very convenient and helpful. However, I just have one possible correction to make in the first few seconds of video: NaCl is an ionic compound. If you take a sample of table salt (or NaCl), it will not be composed of molecules but Na+ and Cl- ions bounded in a cubic crystal lattice. Ionic compound is the right term to be used for all type of salts.

I wish teachers taught this way..

I doubt you will see this, but I just wanted top thank you for all that you do. I can use your videos for my math and science and they always help me tremendously. So thanks- you are my at home science teacher. :)

these guys are really good at teaching in a simple way.. i admired the oxidation-reduction explanations in this video. this is so cool!

Thank you! the way it is explained and how it is presented is easy to understand which also kept my concentration intact throughout the video.

Thank you Khan Academy! My textbook didn't explain why the term oxidization was being used even though no oxygen molecules were involved in a reaction. This explaination helped a lot!

I wish my chemistry teachers could explain like this!! Thank you so much Khan academy

wow I have learned so much from you in just few minutes..

Thank you for finally adding to the chemistry videos. The Gen. Chem. Videos on Khan Academy are severely lacking and aimed for middle school children. Please continue the hard work :). -Proud supporter-

Fantastic Video Sal! Much appreciated! This will definitely help me prepare for pre-med school exams - GAMSAT

Thnx Sal u just made Oxidation and Reduction easy for me!! :D :D :)

well i would really like more chemistry videos, you are great, and your videos have helped me understand lots of thing, not just about chemistry.. but i'd really like more videos about it :) thanks for helping knowledge be easier for everyone, even for brasilians like me! :D

Excellent video.

i love this page because it has saved me so many times, but this video just confused me even more.

Start with the basics and move up from there. Don't stress yourself with over complicated explanations. Try a book that is an easy start. The periodic table- a feild guide to the elements by Paul Parsons and Gail Dixon is a good book for beginners (it's kinda got a rainbow cover with all the element names on it) It mainly has tge uses and a nice little part at the top with the electronic structure on it and fancy stuff like that :)

Hhaahah awesome analogy about being Bernie Madoff'd

how much Valence Electrons have groups (families) 8, 9, and 10?

what's the difference between ionization and oxidation?

which of these substances oxidized or reduced F-1 --> F0

How does he know that sodium has one valence electron? I was referred to this video from a page on the khan site

@user-pp1bv7yr2n

5 жыл бұрын

Atomic number of Sodium:- 11 Electronic configuration:- (2,8,1) Electrons in the last shell:- 1 (Valence Electron)

thank you for explaining it so perfectly

Okay, that's the best and clearest explanation I've seen so far, and, finally, makes sense. Of course, electrons are negative, so a reduction is negative, so.... yeah. Cool. Thanks.

10:44 stuff like that never helped me, but rather made things more hard and cringy to remember oof, I like to remember things in a visually real way

There's another way worth remembering. OPPOSITE ATTRACTS! If there is an electrolysis let's say of solution of NaCl then NaCl molecule is decomposed in water. Cl- (negative ions) head to the anode so they are called because of this ANIONS and Na+ ions migrate to the negative electrode (the cathode) so because of this they are named CATIONS and bear the + (plus) sign.
