The mass of a neutron is approx 1837 times that of an electron. The mass of a proton is similar to that of a neutron.
In the simplest atom, hydrogen, the mass of the nucleus is 1,837 times that of an electron.
In the largest known atom, that of ununoctium, containing 281 baryons (neutrons or protons) the mass of the nucleus is approx 516,200 times that of an electron.
So take your pick: 1,837 to 516,200.
The vast majority of mass in an element is located in the nucleus, comprised of protons and neutrons. Electrons are considered to have almost no mass, although that they exist at all would imply that they must in fact have some mass.
It is about 100,000 times larger
The mass of a nucleus varies according to the atomic number (ie according to what element it is). For hydrogen , the simplest nucleus, the combined mass of the one proton and the one neutron would be equal in mass to 3672 electrons.
There is no simple answer.The mass of a nucleus depends on the number of neutrons and protons in the nucleus. The number of protons in the nucleus depends on the element. Moreover, the number of neutrons can vary between isotopes of the same element.
Electron, proton, nucleus, atom
The nucleus is far more massive than the electron cloud. The mass of the electron cloud is almost negligible compared to that of the nucleus.

The nucleus by far.
The mass of the nucleus makes up most all of the mass of an atom. The only things outside the nucleus are the electrons. The mass of an electron is ~9.11E-31 kg. The mass of an electron is 1/1836 that of a proton.
The proton mass is about 2,000 times greater than the electron mass.
The proton mass is about 2,000 times greater than the electron mass.
Mass ratio proton (neutron)/electron: 1 836
Mass ratio proton (neutron)/electron: 1 836
