hydrogen
yes the mass of an electron is much tinnier fraction of the mass of an atom
There are different isotopes of hydrogen. Assuming you mean the difference in atomic mass between a proton and an electron though, the atomic mass of a proton is about 1836 times greater (approx 1.007 amu), and the neutron is a little more than that (approx 1.009 amu).
Hydrogen has the lowest atomic mass of all the elements. Hydrogen has one proton and one electron. Helium, two neutrons, two protons and two electrons.
The proton is an elementary particle with the mass 1.00727646677 atomic units of mass and the electrical charge +1. It is a hydrogen ion in which one electron is lost. But since hydrogen only has one electron and one proton, a hydrogen ion is just called a "proton", since only a proton is left.
An electron. As the mass of an electron is 00000000000000000000000000000091 kg
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.
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 mass of the whole hydrogen atom includes the mass of an electron as well as the proton. The proton mass is nearly 2000 (actually about 1836) times greater than the electron mass. So, the mass of the hydrogen atom isn't much different from the mass of the proton. It's also possible this question could be about isotopes. Hydrogen has rare isotopes with one or two neutrons in the nucleus. So, the average mass of hydrogen, as measured, is usually a bit more than you would expect from just a proton and electron. However, these other isotopes are very rare and the effect on the mass of a sample of hydrogen would be very small.
Mass ratio proton (neutron)/electron: 1 836
Mass ratio proton (neutron)/electron: 1 836

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.
