The three types of subatomic particles known as the proton, the neutron, and the electron have masses of 1.6726 × 10−27 kg, 1.6749 × 10−27 kg, and 9.1094 × 10−31 kg, respectively. As you can see, protons and neutrons have roughly the same mass, and both of their masses are significantly greater than that of an electron. So, for atoms containing more protons than neutrons, the protons will make up the greatest percentage of mass in that atom. For atoms containing more neutrons than protons, of which there are a whole lot more of, the neutrons will make up the greatest percentage of mass in that atom.
EDIT: Most of the mass in an atom comes from the energy in the Strong Force, which holds the nucleus together. Remember that mass and energy are equivalent.
Protons and neutrons contain most of the mass of an atom. Electrons are much smaller in mass compared to protons and neutrons.
Proton and neutron
Protons mass is 1
Neutrons mass is 1
Electrons mass is 1/1826
The heaviest subatomic particle is the neutron, but the proton is very close.
If you think to the components of an atom the biggest is the neutron but the proton is very close.
Neutrons and protons
NEUTRONS
Proton, neutron, and electron are three subatomic particles that make up an atom. Protons and neutrons are found in the nucleus of an atom, while electrons orbit around the nucleus in electron shells.
electrons, protons, and neutrons. These subatomic particles make up the structure of an atom.
The mass of an atom is mainly due to the nucleus, which contains the protons and neutrons. The electrons, which have a much smaller mass than protons and neutrons, contribute very little to the overall mass of the atom.
Generally speaking, subatomic particles are particles smaller than an atom. There are the three basic ones that make up atoms, and you probably already know that those are protons, neutrons and electrons.If we delve more deeply into the physics of the subatomic world, more and more particles will appear. At one point, there were literally dozens and dozens of different subatomic particles, and they created what was called a particle zoo. Since then, some newer ideas regarding the world of these tiny particles has arisen, and most of the particles in the zoo were recognized as composite particles made up of a just a few fundamental particles.Begin learning about subatomic particles by developing an understanding of protons, neutrons and electrons. Then find out what makes them up, and move from there to the number and nature of fundamental particles.
Large positively charged subatomic particles are called protons. They are found in the nucleus of an atom and have a charge of +1.
These particles are the protons and neutrons.
These particles are protons and neutrons.
This particle is the neutron: 1,00866491600(43) amu.
Protons and neutrons.
Electrons are negatively charged subatomic particles, but have almost no mass. The mass of an electron is about 1/2000 that of a proton or neutron. The neutron is the most massive of the subatomic particles at 1.6755 x 10-24 grams.
These particle are neutrons and protons; they are located in the atomic nucleus.
These particles are the electrons.
It is usually considered to be neutrons and protons that hold most of an atom's mass, however there is one theoretical subatomic particle that is used to help explain mass, called the higgs boson particle.
Electrons
just electrons
The major contribution to the mass of an atom is from protons and neutrons; electrons have a known but negligible mass.
These particles are: proton, neutron, electron.
