Why do protons and neutrons have different mass?

the differences between the proton (udu) and neutron (udd) is that the has neutron’s second down quark is heavier than the proton’s second up quark. So the greater mass of this down quark gives the neutron a greater mass than the proton.

How does the mass of the neutron compare to the mass of the proton?

The mass of a neutron is slightly greater than the mass of a proton, which is 1 atomic mass unit (amu). (An atomic mass unit equals about 1.67×10−27 kilograms.) A neutron also has about the same diameter as a proton, or 1.7×10−15 meters.

Why do neutrons have the most mass?

The neutron-proton mass difference may seem trivial but it has momentous consequences, because mass is a form of energy (remember E = mc2). The neutron, as it happens, has a little more mass (and thus energy) than a proton and an electron combined.

Why mass of a proton is much larger than mass of the quarks that make up the proton?

A proton’s mass is more than just the sum of its parts. Protons are made up of even smaller particles known as quarks. It might seem reasonable that simply adding up the quarks’ masses would give you a proton’s mass.

What is the difference between up quarks and down quarks?

Protons and neutrons are composed of two types: up quarks and down quarks. Each up quark has a charge of +2/3. Each down quark has a charge of -1/3. The sum of the charges of quarks that make up a nuclear particle determines its electrical charge.

How does the mass of a proton compared with the mass of an electron?

proton, stable subatomic particle that has a positive charge equal in magnitude to a unit of electron charge and a rest mass of 1.67262 × 10−27 kg, which is 1,836 times the mass of an electron.

Do the proton and neutron have exactly the same mass?

The protons and the neutron have similer, but not identical, masses. Either of these particles has a mass approximately 2000 times greater than the mass of the electron the combination of the protons and the neutrons make up the bulk of the mass of the atom.

Do neutrons and protons have the same mass?

Protons and neutrons have approximately the same mass. However, one proton is about 1,835 times more massive than an electron. Atoms always have an equal number of protons and electrons, and the number of protons and neutrons is usually the same as well.
