The correct answer is neutron not electron
The mass of an electron is approximately 9.1 * 10^-31
Which lighter than proton whose mass is 1.67 * 10^-19 and which is approximately equivalent to the mass of neutron
Know it that the number of protons is equal to the number of electrons
And not the mass
But the number
