video description

Rating: 4.5; Vote: 2
Hank brings us the story of the electron and describes how reality is a kind of music, discussing electron shells and orbitals, electron configurations, ionization and electron affinities, and how all these things can be understood via the periodic table. Pssst. we made flashcards to help you review the content in this episode! Find them on the free Crash Course App! jonnection: Came here from Quantum mechanichs thinking perhaps I ought to give Chemistry another chance, perhaps now as an adult I could be interested and ready to listen. Nope. Chemistry in this series (and other YT videos) is just rapid fire recipe reading bs that I always loathed in school.

Bro, the facts of reality are so condensed to give way to your obnoxious blabla. how does that contribute to the understanding of what I think isn't so hard. if not constantly compared to other things, which can't be related to anyways, if not understood what's the underlying principal behind it all in the first place?
Thank you for doing those videos honestly and I see you like to do so, but I would stick to the script a little more.

So. electrons are a wave and there can be numerous waves circulating around the nucleus at different stages of -excitement- levels. and when you want to understand it any further you'll have to get a PhD, and even then after studying physics for almost a decade of your life, your conclusion will be -if you think you understand quantum mechanics you really don't understand quantum mechanics-. it's futile!

Course progression: -
Vid 1: Learn to crawl. -
Vid 2: Crawling forwards, backwards, turning and varying speed. -
Vid 3: Learning to stand up. -
Vid 4: First walking steps while holding on to tables, railings or someone's hand. -
Vid 5: Competing in the decathlon while sampling magic mushrooms between events. -
Can't wait for Vid 6.

It's sort of difficult to understand these analogies if you don't know anything about music. I hope later Crash Course vids are a bit better, way more time was given to the music analogy than to actually explaining the order of shells and how they differ from each other, or why they have the names they do

One question.
If an atom loses an electron, I understand it becomes a positively charged ion.
However, how an atom that had one electron removed would differentiate from an atom that did not lose any electron?
What are the differences that you can see?
Thank you.

Ok so I have a question: -
as for the example of oxygen, what's the difference between O (neutral oxygen atom) and O-2 (negatively charged oxygen ion) in the real world? do those atoms behave differently? -
Thank you.

Physicists: we invented quantum mechanics so we can predict electron configurations before discovering them.
Chemists: Let's put them in a table and force people to memorize it.

This presentation of electron is like listening to a symphony. You feel good but learn nothing. But still he is the best, but he is reading off a prompter and has no clue what its all about!
