Mass Spectrometry

009 - Mass Spectrometry
In this video Paul Andersen explains how a spectrometer was used to identify the presence of isotopes. This modified Dalton's original atomic theory because atoms of the same element had different masses. The functional parts of a mass spectrometer are detailed including the ionizer, mass analyzer and the detector. A simulation of Chlorine isotopes along with an average atomic mass calculation is included.

    Wow, you've taken something that I assume is incredibly complex, explained it in 8 minutes and I actually understood it. And I sucked at chemistry.

    Science isn't hard. It, like math, depends on the educator. Most educators suck. Especially people who call themselves 'science communicators' (see: twenty something 'camera ready' girls who are barely undergrad's on buzzfeed like channels who wear t-shirts that read 'i fucking love science' or something along those lines. They're as negligent as the old uppity teacher who thought the class was hopeless and didn't try, because unlike them they assume the entire class is mentally retarded and needs babyspeak.) People like this guy just explain shit the way it is, and if things are explained in a straight forward way there's no reason to not understand them!

  • @yosimba2000

    @yosimba2000

    8 жыл бұрын

    +rustyjeanz Abundance is just the fraction of that specific isotope from all atoms of that element. So say you have 10 atoms of Chlorine. Of these 10 Chlorine atoms, 7 of them have atomic weight of 35, and 3 of them have atomic weight of 37. So the abundance of Chlorine 35 is just # of Chlorine 35/ All Chlorine, which is 7/10 = 0.7, which is your abundance. For Chlorine 37, the abundance is 3/10 = 0.3 Notice the abundance is essentially just the chance of getting that type of atom. You have 0.7, or 70% chance to get Chlorine 35, and 0.3 or 30%, to get Chlorine 37. Percent chance * Weight + Percent chance * Weight is what is called the Expected Value in statistics, which gives the average value of a Chlorine atom.
