A proton has a size of 1.23x10^-11 and an electron has a size of 1.4x10^-8. How many times smaller is an electron than a proton? Show your work.
If I divided 1.23x10^-11 and 1.4x10^-8, wouldn't 1.4x10^-8 be the numerator or the denominator?
something is really wrong with your data. you have the electron almost 1000 times larger than the proton.
how many times smaller is an electron?
ANS= diameter electron/diameter proton.
but your data is really wrong. http://en.wikipedia.org/wiki/Orders_of_magnitude_%28length%29
It is just an example.
