Explanation / Answer

Protons andelectrons have charges of the same magnitude but opposite sign. (True )
Protons have aboutthe same mass as neutrons.(true)
Some atoms don'thave any protons.( True)              Example is 1H 1
Protons and neutronshave charges of the same magnitude but opposite sign. ( False )Since neutrons are chargeless particals. So the false statement is Protons and neutrons have charges of the same magnitudebut opposite sign. mass of electron m = 9.11*10^-28 g Mass of proton , m' = 1.672 * 10^-24 g m' / m = 0.1835 * 10^ 4           =1835 So the required answer is 1835 So the false statement is Protons and neutrons have charges of the same magnitudebut opposite sign. mass of electron m = 9.11*10^-28 g Mass of proton , m' = 1.672 * 10^-24 g m' / m = 0.1835 * 10^ 4           =1835 So the required answer is 1835
