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.

The stronger force between protons and neutrons in a small nucleus and a larger nucleus?
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.
What has the smaller mass protons electrons or nutrons?
Electrons have a smaller mass than both protons and neutrons. Both protons and neutrons are over 1800 times as massive as electrons.
Are elections bigger or smaller then neutrons and protons?
Electrons are smaller in mass, but equal to protons in charge, although with the opposite charge, and bigger than neutrons in charge.
The instability that occurs in larger nuclei is caused by the fact that?
the strong nuclear force doesn't fall off much in a small nucleus
In subatomic particles do protons and neutrons have the same mass?
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.
Are electrons larger than neutrons and protons?
no. protons and neutrons are MUCH larger than electrons.
Are protons bigger than neutrons?
Yes, neutrons are larger than protons.
Heavier nuclei have more neutrons than protons?
As a general rule yes, larger molecules do tend to have more neutrons than protons.
Are electrons protons or neutrons the smallest particles if not what arew?
protons/neutrons are made of quarks which are smaller than electrons. electrons are smaller than protons and neutrons.
How are neutrons and protons different?
Protons are positively charged and neutrons are neutral.
Is a calcium atom larger than a barrium atom?
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 what?
An atom that has more neutrons than protons is called an Isotope.
Are electrons bigger than neutrons and protons?
Electrons are 1,836 times lighter than protons. A proton is 99.8% the mass of a neutron
What Make up 50 percent of the atomic mass of the nucleus?
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.

What statement is true about atoms protons neutrons and electrons?
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.
Larger a nucleus is the greater its?
the larger the nucleus is, the greater the cell's mass
What are the particles of subatomic particles?
These particles are: proton, neutron, electron.
