1.67492729(28)×10 kg Is the mass of a neutron whick is actually larger than a proton. Neutrons have no electrical charge so as a extra I have a science joke -A neutron walked into a bar and
asked how much for a drink. The bartender replied, "for you, no charge."
Hope this helps:)
From zaibybaby
Neutrons have a mass slightly greater than that of protons, approximately 1.675 x 10^-27 kg. While they are lighter than most atomic nuclei, their mass is significant in the context of particle physics.
That depends on the context. A neutron has approximately the same mass as a proton, and approximately 1800 times the mass of an electron. Whether that is negligible depends on the problem at hand.
Compared to the size of an atom, No! If an atom were the size of an average sized home, a neutron would be the size of a speck of dust.

What is the mass of an atomic nucleus?
The mass of an atomic nucleus is typically expressed in atomic mass units (u). The mass of a nucleus is determined by the total number of protons and neutrons it contains, with protons and neutrons contributing to the majority of the mass, while electrons have negligible mass compared to nucleons.
Do Electrons have weight?
Yes, electrons have an extremely small amount of mass, about 9.11 x 10^-31 kilograms. This makes them much lighter than protons or neutrons in an atom.
What subatomic particle contributes alomst no weight to an atom?
The subatomic particles that contribute most almost no weight to an atom are electrons at various energy levels. Isotopes of the same element differ from each other only by the number of neutrons.
What is the number of neutrons in an atom affects the atomic what?
The number of neutrons in an atom affects the atomic mass of an element. Neutrons contribute to the overall mass of the atom but do not affect its chemical properties.
What are the main parts of an electron?
An electron consists of three main components: mass (negligible compared to protons and neutrons), charge (negative), and spin (intrinsic angular momentum).
Why is mass number calculated with only the protons and neutrons and not electrons?
Because the mass of electron is negligible when compared to the mass of protons or neutrons.
What is this element atomic mass?
mass of protons + mass of neutrons present in the element (as the mass of electrons is practically negligible)
What determines the mas of an atom?
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.
Where is most of the mass of an atom contain?
in the nucleus of an atom -proton and neutrons , electrons in the orbit has the negligible mass.
What particle contributes a negligible amount to the atomic mass?
There are a number of particles of particularly low mass. Electrons have much less mass than either protons or neutrons, and so are negligible in calculating the mass of an atom. However, electrons are still much heavier than neutrinos or photons, which are even more negligible in mass.
Why don't he include the electron in atoms mass?
when compared to the mass of protons and neutrons, the mass of the electrons is negligible and hence not included in atomic mass.
Why is the atomic mass generally used to refer to just the number of protons and neutrons?
The weight of an electron is negligible compared to that of protons and neutrons.
Which subatomic particles makes up most of the mass off the atom?
The major contribution to the mass of an atom is from protons and neutrons; electrons have a known but negligible mass.
Which two particles does the atomic mass number represent?
The atomic mass number represents the total number of protons and neutrons in an atom's nucleus. It does not include the electrons because their mass is negligible compared to protons and neutrons.
What and what make up the atomic mass?
The atomic mass of an element is the sum of the number of protons and neutrons in the nucleus of an atom. Protons have a positive charge and neutrons have no charge, contributing to the overall mass of the atom. The number of electrons, which have a negligible mass, is not included in the atomic mass.
What product of nuclear decay has mass but no charge?
Neutrons have no charge, but have mass. This is also true of neutrinos, though the mass is considered negligible for most purposes.
What is the mass of an atom found by?
The mass of an atom is primarily determined by the combined masses of its protons, neutrons, and electrons. Protons and neutrons contribute most of the mass since electrons have negligible mass. The exact mass of an atom can be found by adding up the masses of its protons, neutrons, and electrons.
