no. of electrons (mass of 1 electron)= mass of 1 proton
no. of electrons ([tex]9.109 x 10^{-28}[/tex] grams)= [tex]1.672 x 10^{-24} [/tex] grams
no. of electrons= [tex]1.672 x 10^{-24} [/tex] grams / [tex]9.109 x 10^{-28} [/tex] grams
no. of electrons= 1836
1836 electrons should be placed on one side of the seesaw to balance it if the other has 1 proton on it.
