The neutron, which is slightly more massive. The neutron is composed up two down quarks and one up quark (charges of -1/3 and 2/3 [in terms of proton charge], respectively) and the proton is composed of one down quark and two up quarks.
The neutron has a mass very close to the mass of proton (but not identical).
The neutron has the biggest mass; but the mass of proton is very close.
The neutron has the biggest mass; but the mass of proton is very close.
In the atom the heaviest particle is the neutron but the proton is close.
No. Its not even close. An alpha particle is two neutrons and two protons, while a beta particle (from beta- decay) is just an electron, which has one 1836th the mass of a proton.
A neutron has about the same mass as a proton.
A particle that has a mass of 1 and a charge of 1 plus is a proton.
The masses of all three particles are different The masses of a proton and the mass of a neutron are very close, however. The mass of an electron is much smaller than the mass of a proton or neutron.
An alpha particle is about four times heavier than a proton.
The particle with one unit of positive charge is Proton. Answer Proton
This particle is the neutron.
No, that would be a neutron. A proton is a nuclear particle with a mass of 1 AMU and a 1+ charge
