atomic units. A proton has a mass of 1 atomic unit, and so does a neutron. the mass of an electron is very small, and almost negligible
protons --- rel. mass 1 amu, rel. charge +1, location in the nucleus. neutrons --- rel. mass 1 amu, rel. charge 0, location in the nucleus. electrons --- rel. mass 0 amu, rel. charge -1, location outside the nucleus.
The nucleus is made up of protons and neutrons. Most of the elements with low atomic numbers are equally protons and neutrons. However, as elements get heavier they will have more neutrons than protons, and since each weigh the same amount (1 atomic mass unit) these nuclei will get most of their weight from the neutrons.
You would use the unit of measure called "kilograms" to measure the mass of an elephant.
Protons and neutrons are in atomic nuclei, while electrons are located outside atomic nuclei in various probabilities of energetically favored states. Quarks are the fundamental particles that compose the hadron family of particles, of which protons and neutrons are members. Thus, you better believe quarks are found in atomic nuclei! In fact, because of the way the strong nuclear force acts on quarks, they can never be found on their own they are not found on their own at low energies but it is possible that they can become free at extremely high energies, as is the case in the hypothetical quark-gluon plasma. As we can observe them, however, they're always in protons and neutrons (or the various other hadrons).
Sub-atomic particle is the proper term to describe your question. We generally know atom construct from proton, neutron and electron while proton is positron and neutron. To even smaller scale, it is the Quark that is the building block of the matter.
Protons and neutrons have approximately the same mass in an atom. Protons have a mass of about 1 atomic mass unit (amu), while neutrons have a slightly larger mass of about 1 amu.
Protons and nuetrons Dom says: Protons and Neutrons.
To calculate the atomic mass of an atom, you would add the number of protons and neutrons together. Protons and neutrons each have a mass of approximately 1 atomic mass unit (amu). The sum of the protons and neutrons will give you the atomic mass of the atom in atomic mass units.
number of protons and number of neutrons
The atomic mass unit of protons and neutrons is approximately 1.67 x 10^-27 kg. This unit is used to express the mass of subatomic particles in atomic physics.
In an atom, there are 3 types of particles: protons, neutrons and electrons.Theoretically, protons and neutrons weight 1 Atomic Mass Unit. An electron weights 1/1836 of an Atomic Mass Unit. Therefore, in an atom, electrons weigh the least.
No, it's about 1/2000th of an amu (atomic mass unit). Protons and neutrons are 1 amu.
The atomic mass unit of an atom is the sum of the protons and neutrons in its nucleus. In this case, with 8 protons and 9 neutrons, the total atomic mass unit of the atom would be 17. The number of electrons does not significantly affect the atomic mass unit of an atom.
To the find the mass number of an atom you add the protons and neutrons. Meaning that the mass number of this atom is 12.
the mass of an atom of a chemical element expressed in atomic mass units. It is approximately equivalent to the number of protons and neutrons in the atom (the mass number) or to the average number allowing for the relative abundances of different isotopes.
In science the basic unit is the atom which is composed of neutrons, protons, and electrons. Electrons are generally considered to small to count as part of the mass. Atomic mass is the sum of neutrons and protons. For example: Oxygen has 6 protons and, in its natural state, 6 neutrons. This means that its atomic mass is 12.
The atomic mass is the sum of the number of protons and neutrons in the nucleus because protons and neutrons have a mass of approximately 1 atomic mass unit each. Electrons are much lighter and do not significantly contribute to the overall mass of the atom.
