Ashish Posted January 20, 2008 Share Posted January 20, 2008 The elementary charge (symbol e or sometimes q) is the electric charge carried by a single proton, or equivalently, the negative of the electric charge carried by a single electron It has a value of 1.602 176 487 × 10^(-19) Coloumb. So is there any elementary mass Link to comment Share on other sites More sharing options...
thedarkshade Posted January 20, 2008 Share Posted January 20, 2008 yes there is: [math]9.1 \times 10^{-31}kg[/math] Link to comment Share on other sites More sharing options...
Ashish Posted January 20, 2008 Author Share Posted January 20, 2008 Isn't it for Atomic Mass Unit 1 amu = 1.660538782(83)\times 10^{−27} kg Link to comment Share on other sites More sharing options...
thedarkshade Posted January 20, 2008 Share Posted January 20, 2008 No, the atomic unit mas is [math]1.6605 \times 10^{-27}kg[/math] and that's just to make the calculations easier. The elementary mass is what I posted above! Link to comment Share on other sites More sharing options...
Ashish Posted January 20, 2008 Author Share Posted January 20, 2008 As there is a charge quantization so as well for mass also or what? Link to comment Share on other sites More sharing options...
thedarkshade Posted January 20, 2008 Share Posted January 20, 2008 Listen, the elementary charge like you posted is: [math]q_e=1.609 \times 10^{-19}C[/math] that is the charge of an electron or a proton. The smallest charge existing. And the elementary mass is the mass of the electron which is: [math]m_e=9.1 \times 10^{-31}kg[/math]. You mention atomic unit. That equals [math]1.6605 \times 10^{-27}kg[/math] and it has been taken by convention to make the calculations easier! Link to comment Share on other sites More sharing options...
Ashish Posted January 20, 2008 Author Share Posted January 20, 2008 No I was saying that charge occur only in quanta i.e. q = ne so is there anything about mass quantization Link to comment Share on other sites More sharing options...
thedarkshade Posted January 20, 2008 Share Posted January 20, 2008 Nah, don't think so. At least I have not heard so! Link to comment Share on other sites More sharing options...

timo Posted January 20, 2008 Share Posted January 20, 2008 So is there any elementary mass No. Link to comment Share on other sites More sharing options...
thedarkshade Posted January 20, 2008 Share Posted January 20, 2008 http://en.wikipedia.org/wiki/Plank_mass I don't get yourdadonapogos, [math]9.1\times 10^{-31}kg[/math] is much smaller than [math]2.176\times 10^{-8}kg[/math] and elementary means the smallest one possible. I don't understand the reason of you post! Link to comment Share on other sites More sharing options...
Klaynos Posted January 20, 2008 Share Posted January 20, 2008 No. I think we should all note this... Link to comment Share on other sites More sharing options...
Ashish Posted January 20, 2008 Author Share Posted January 20, 2008 I mean to say that is there any small elementary particle which can be used as an integral one. Link to comment Share on other sites More sharing options...
swansont Posted January 20, 2008 Share Posted January 20, 2008 I mean to say that is there any small elementary particle which can be used as an integral one. No, there is no elementary quantized unit of mass. At least not that I've heard of. Link to comment Share on other sites More sharing options...
Roberto Posted February 27, 2012 Share Posted February 27, 2012 So than may I ask what the definition/use of elementary mass unit is? Ive been wondering since I was introduced to the concept. Link to comment Share on other sites More sharing options...
swansont Posted February 27, 2012 Share Posted February 27, 2012 So than may I ask what the definition/use of elementary mass unit is? Ive been wondering since I was introduced to the concept. Under what scenario was this a concept that could be introduced? Link to comment Share on other sites More sharing options...
Roberto Posted February 28, 2012 Share Posted February 28, 2012 solid state chemistry and Im aware of its value. even roughly aware thats its obtained as (m©/12)/(6.02E23), correct me if Im wrong because I did the calculation on the graphing calc and got 1.66261074E-27. Im using m©=0.0120107kg. Link to comment Share on other sites More sharing options...

Im using m©=0.0120107kg. That's a standard mass unit (the atomic mass unit), not elementary mass, i.e. a quantized unit, in keeping with the subject of the OP. amu is used because it is scale-appropriate for nuclear, atomic and molecular calculations.
