Electrons.
Neutrons have almost the same mass as protons. They are both subatomic particles found in the nucleus of an atom and are collectively referred to as nucleons. The mass of a neutron is only slightly greater than that of a proton.
A neutron and a proton almost have the same mass. A neutron and 1,840 electrons almost have the same mass.
Protons and neutrons have about the same mass, but electrons are much, much lighter.
The number of protons must be the same.
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.
no
The atomic mass of an element is determined by the number of protons and neutrons in its nucleus. Protons and neutrons have almost the same mass and contribute to the overall mass of the atom. Electrons, on the other hand, have negligible mass compared to protons and neutrons and do not significantly affect the atomic mass.
Protons and neutrons have almost the same mass.
No, the atomic mass consists of protons, but the atomic mass consists of both protons and neutrons.
No, atomic mass and atomic number are not the same thing. Atomic mass represents the average mass of an atom of an element, which includes the mass of protons, neutrons, and electrons. Atomic number, on the other hand, represents the number of protons in the nucleus of an atom, which also determines the element's identity on the periodic table.
No. The mass of neutrons and protons are about the same. The mass of an electron is about 1/1800th the mass of a proton.
Each proton has the same mass as any other proton, as long as the proton is not in motion. Motion close to the speed of light can increase the mass for quantum theory reasons.
