mass of proton & neutron = 1.678*10^-27.
while that of electron is = 9.1*10^-31.

I agree with sandeep.

@sandip:but mass of electon is 1.6*10^-19

Ranjitha said:   1 decade ago
@Mukesh:charge of electron=1.6*10^-19

Hello guys question is on radius not mass or charge. :).

Which is the largest ?

Praveen said:   1 decade ago
You are right Amuthan. The question is about its radius not the mass or charge.

Radius of Neutron: 1.113284057367 x10^-15 m
Radius of proton : 1.112772961016 x10^-15 m
Radius of electron: 9.087345835484 x10^-17 m

So, electron is the smallest.

Just FYI.

Mass of an electron is 9.1*10^-31 kg.

Mass of a proton is 1.6*10^-27 kg.

Charge of an electron is -1.6*10^-19 C.

Charge of a proton is 1.6*10^-19 C.

Proton & neutron joint, so it was big size.

But electron is separate.
