Chemistry Tutorial on 36 Chemical Elements

[@Iluminacion32]

What an extraordinary Master and pedagogue behind all these videos. I cannot wait to watch all of them. Thank you so much for your greatness, Ian Stuart.

great videos, thanks for your posting videos in good understanding manner. good job, keep it up sir.ian Stuart

Hello Ian. Very good series of videos. Can you index them or make an ordered playlist? tracking the order that they should be played is difficult. Great job otherwise!

[@EatShiteAholes]

well done! and very interesting.

[@harshrathod50]

Very good explanation.

[@SirMonkeyoftheBrook]

Thank you for making these

There is not only 92 elements, in fact in the current Periodic Table there is 118, but what you mean are elements in nature, but even then, there have been disvorered 98 chemical elements.

A fine video series BUT there is an error, at about 19:39. Water Vapor is the earth's most abundant GREENHOUSE gas and NOT Carbon Dioxide. Look it up, folks.

Again, great vid series. Keep up the good work. A few points addressing the above, if I may: 1) As the IR spectral 'absorption'(and emission) lines in CO2 is roughly comparable to water vapor, CO2 is not really a "greater" CO2 gas, As it is, water vapor also exists in far grater quantities or concentrations in the troposphere than CO2, and CO2 in its concentration really only qualifies as a "trace gas" in the atmosphere. Ever wonder why dry, deserts cool more quickly than humid coastal cities at the same latitude? Yup, water vapor in the air exhibiting the "green house gas" effect keeps humid locales 'warmer due to reduced nighttime cooling via longwave IR 'blocking' by water vapor ' ... we see that here my part of Texas when we get extra dry air coming in from the desert southwest versus the usual moist Gulf of Mexico air masses. These are long known meteorological effects, check any good meteo text book! 2) CO2 *is* compressible. Curious What makes you think it isn't as ALL gases are compressible ... Recall those little CO2 canisters used in pellet pistols and pellet rifles? Yup, compressed CO2 (as they are labeled even.) Also, CO2 is used to put the fizzle in coke and Pepsi via an external CO2 compressed gas cylinder on soda fountain dispensing machines. 3) The term "forcing" they use is one borrowed (stolen?) from meteorology and in meteorology can refer to sunlight or orographic lift or the wind even. One can replace the word "forcing" with the term "factor" for better clarity, I think. -uploadj

1) Re: "why deserts cool more quickly" etc.. This is pretty basic. Wind can act a "transport" of warm air, but, I'm not assuming that. Take various coastal cities in California, when the wind is light and/or from offshore .. definitely drier air AND temps plunge further at night (as well as being warmer during the day too; no greenhouse gas -WV- to impede longwave IR.) I also gave an example of my area here in Texas *when* we get a drier air mass into our area from the southwest (from Mexico), but I guess didn't make that point effectively.. I am revealing nothing new here in terms of meteorology, any good meteo knows these things (or should! hence my reference to meteo text books.) 2) Once condensed, H2O of course exhibits completely different characteristics. I'm only considering side by side effects with CO2 in the IR absorption/emission spectra (where green house gas effects are noted). Things get a lot more complicated when considering a climate scenario with the complete "water cycle" as it is termed in the sciences. CO2 gas compressability (like any gas) is not a subject for debate, rather, it is fact A quick trip to a sporting goods store and purchase of an CO2-powered pistol is witness to this. (I don't understand this angle of discussion. See below, maybe it is my choice of terms?) A material or substance "phase change" (gas to liquid or liquid to solid even) has not been considered in this discussion; only gaseous water (water vapor, which is a gas, as opposed to liquid water which includes clouds) contrasted with CO2 (which exists as a gas under all conditions in the atmosphere here on earth. Even at the poles, even though temps might approach and reach the condensation point of CO2, the vapor pressure is so low that CO2 remains as a gas.) -iploadj

can you possibly explain what is really meant by "charged particles"... what does the "charge" actually consist of? As we are down to the particle level, what exactly is a "charge"? It will be "energy" but even then "energy" per se means little.

[@AlternativeDesign100]

thanks.

[@AlternativeDesign100]

can you check that link? It takes me to my own youtube editor page, not to a video. Most bizarre. Many thanks.

[@AlternativeDesign100]

very strange. I'll try the link with my iphone. Won't load this thread anymore with this issue! Weird all the same (I even tried another browser). The link contains the word "edit"... I wonder if it will work for you as you are routed to your editing page and of course I won't be. Anyway, apologies for loading the thread with this. I'll find a way.

[@kadalikishore7170]

post many videos why cant i see other videos.....after 2.1 i cant se 2.2 ...plxx create playlist....

[@jsa326]

This is a cool vid

[@abdalkaderboukhris166]

I will subscribe ur chanle for this useful vid. thnx

12:44. A nickel is only 25% nickel

[@jasonbourne220]

you said 'meet the elements' not meet 36 elements. must be a mistake.
