Noble gas configuration | Electronic structure of atoms | Chemistry | Khan Academy

How to write electron configurations for atoms and monatomic ions using noble gas configuration.

Chemistry on Khan Academy: Did you know that everything is made out of chemicals? Chemistry is the study of matter: its composition, properties, and reactivity. This material roughly covers a first-year high school or college course, and a good understanding of algebra is helpful.

About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

1. where is sal
2. that periodic table seems inaccurate.

I was waiting on some deep voice to appear but nvmmmm LOL

[zekematthews]

I prefer the softer bedroom voice and the clean hand writing. Thanks for the video.

[misanamuka]

I understood it perfectly. Lol it was not hard as I thought, thanks.

[saintofchelseathomascarlyl]

her voice is really pleasant, i listen to her with headphones and its very relaxing i especially enjoy how the echo of her voice is metallic and when she scratch on the tablet with the electronic pen

I have Chemistry final test tomorrow, and i looked for many videos to understand it but there were not too clear for me. but now with you video i did understand it in just 5 mins
Thank you so much

"Sil-ican"
No, its Sil-a-con, as in Khan in Star Trek.

Thank you I understand the noble gas configuration a lot better now but would it be wrong to leave the valence electrons, for the noble gas configuration of Calcium as [Ar]4s^2 or do we always have to change it to [Ar]? If yes do we do this to all group 2 elements, or what elements do we change this for?

[sunnyside]

Thank you thank you thank you thank you

[dorothywinston]

Hey, thanks for the video; however, I couldn't understand anything. I thought it was for beginners, I could understand Khans lectures, but I'm off with yours; maybe I should watch the video more times.

[mohammednourinjerini]

Your explanation is interesting and beneficial so much.

[johnpatrickugsang]

I dont get why you are complaining about another voice in explaining the video. Why cant you be thankful that she could help you in any way. If ever you're still complaining her voice then dont watch the video. Easy as that. Also, we dont know that the original VA is sick or is busy doing important things. Please be more understandable HUMAN being

[DaiLoDong]

best shit. got me like 2 free questions on my final

[khalilac]

The noble gases are gone? Where did they go? Im confused

[anuraj]

Can you please tell, what is the Noble gas for cancer enthalpy

[joelntagara]

If Cl losses 2 electrons and becomes Cl^2+ then what happens to Zn ?

[SuperCouch]

I have 8 packets of chemistry work due tomorrow at the beginning of class

[LouWilliams-ov]

would you still call it calcium at that point?
