Slightly more than that of a proton plus an electron.
No; the mass of proton is similar to the mass of neutrons.
Atomic mass = mass of protons + mass of neutrons.
Neutrons have no charge, but they do have mass.
No, neutrons + protons = mass
Mass number is about the neutrons and protons. The total of neutrons and protons.
Mass of an atom = mass of protons + mass of neutrons
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.
The major contribution to the mass of an atom is from protons and neutrons; electrons have a known but negligible mass.
The mass of an atom is primarily determined by the sum of its protons and neutrons. To find the mass of an atom with 13 protons and 14 neutrons, add the total number of protons and neutrons together: 13 protons + 14 neutrons = 27. The approximate mass of this atom would be 27 atomic mass units (amu).
The sum of all protons and neutrons - Apex Learning
Neutrons have no mass at all and have no charge on them.
The mass of an atom is determined by the combined mass of its protons, neutrons, and electrons. Protons and neutrons are the primary contributors to the mass, while electrons have a negligible mass in comparison.
