Yes, in general. All hydrogen atoms contain one proton, most with no neutrons and all neutral atoms with one electron - and the electron has a much smaller mass. Some hydrogen atoms contain one (or, rarely, two) neutrons and so are heavier. But on average the atom has a mass much the same as a proton.
The mass of a proton is approximately equal to the mass of a neutron. Both particles have nearly the same mass, which is about 1.67 x 10^-27 kilograms each.

How does the mass of an electron compare to that of a neutron?
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.
What two subatomic substances have a mass of about 1 amu?
Proton and neutron - both have a mass of about 1 atomic mass unit (amu).
What particle has the same mass as a neutron?
A positron, a neutron, a single proton, and a single electron are all considered to be equal in mass, however, a positron is generally referred to as an "anti-electron", as it travels at the velocity of light (like an electron), an has a positive charge (+1e, as opposed to an electron, which carries a negative charge, i.e: -1e).
Which has a subatomic particle of a mass of 1.67 times 10-27 kg?
That mass is approximately equal to the mass of a proton or neutron, which are subatomic particles found in the nucleus of an atom.
Which subatomic particle is nearly equal to the masses of the other two subatomic particles added together?
The neutron has a mass that is nearly equal to the combined mass of a proton and an electron. This is due to the fact that the neutron is slightly heavier than the proton, while the electron has a much smaller mass.
How does the mass of a electron compare to the mass of a proton and neutron?
Mass ratio proton (neutron)/electron: 1 836
How does the mass of a proton compare to the mass of a neutron and an electron?
Mass ratio proton (neutron)/electron: 1 836
How do a proton and neutron compare?
they have adout the same mass
How does the mass of an electron compare to the mass of the neutron?
The electron has only a small fraction of the mass of the neutron. The neutron is about 1837 times as massive as the electron. The proton is just a tiny bit less massive as the neutron, so the proton and neutron are said to have about the same amount of mass.

Which particle has a mass that is approximately the same as the mass of a proton?
A neutron has a mass that is approximately the same as a proton, both with a mass of about 1 atomic mass unit.
How does mass of an electron compare to the mass of protons and neutrons?
Mass ratio proton (neutron)/electron: 1 836
If a proton had a mass of 1 what is the mass of an electron and neutron relative to the mass of the proton?
An electron has a mass of approximately 0.0005 times the mass of a proton, while a neutron has a mass that is slightly greater than that of a proton.
Does a neutron have the same mass as an electron or a proton?
A neutron has a mass approximately equal to that of a proton, which is about 1,836 times the mass of an electron.
How do the masses of one electron compare to the masses of protons and neutrons?
mass of electron = 1/1836 mass of proton (or neutron)
What is the mass of an electron compared to the mass of a proton or neutron?
Mass ratio proton (neutron)/electron: 1 836
How does the mass of the neutron compare with the mass of the proton?
The mass of a neutron is slightly greater than the mass of a proton. The neutron has no electric charge while the proton has a positive charge (+1 elementary charge). The mass of a neutron and a proton are 1.67492729(28)×10−27 kilograms and 1.672621637(83)×10−27 kilograms respectively. That makes the neutron about 25/10,000ths more massive than the proton.
