Neutrons have greater mass. A neutron rest mass is 1838 electron volts. A proton rest mass is 1835 electron volts.
In terms of physical size, this question may not be meaningful. Protons and neutrons are comprised of three quarks each, and their masses apparently are not conserved.
In a small nucleus, such as oxygen, xenon, or any of the lighter elements, the strong force generated by the protons and neutrons is stronger than the repulsion between protons, and the nucleus holds together. In a larger nucleus, such as uranium, curium, or the heavier elements, the strong force isn't strong enough to hold it together, and the electromagnetic force pulls it to pieces.
Electrons have a smaller mass than both protons and neutrons. Both protons and neutrons are over 1800 times as massive as electrons.
Electrons are smaller in mass, but equal to protons in charge, although with the opposite charge, and bigger than neutrons in charge.
the strong nuclear force doesn't fall off much in a small nucleus
The masses of protons and neutrons are very close, but not the same. A proton is about 1.001378 times more massive than a neutron.
no. protons and neutrons are MUCH larger than electrons.
Yes, neutrons are larger than protons.
As a general rule yes, larger molecules do tend to have more neutrons than protons.
protons/neutrons are made of quarks which are smaller than electrons. electrons are smaller than protons and neutrons.
Protons are positively charged and neutrons are neutral.
Calcium contains 20 protons, 20 neutrons and 20 electrons (on average). Barium has 56 protons 81 neutrons and 56 electrons (again, on average). So, Barium is much larger.
An atom that has more neutrons than protons is called an Isotope.
Electrons are 1,836 times lighter than protons. A proton is 99.8% the mass of a neutron
Well, this is not exact, but smaller atoms have about the same number (and mass) of neutrons and of protons. Heavier atoms have a larger percentage of their mass in neutrons.Well, this is not exact, but smaller atoms have about the same number (and mass) of neutrons and of protons.

Several come to mind. They are both found in the nucleus of an atom. Protons have a positive charge, while neutrons have no charge. They are nearly the same size, though neutrons are a bit larger. The sum of the protons and neutrons in an isotope of an element is its mass number.
the larger the nucleus is, the greater the cell's mass
These particles are: proton, neutron, electron.
