The average mass of a neutron is
1.674929 u :)
Can I get brainlyest please

Answer: Average mass of proton is 1.007276 u  and that of neutron is 1.008664 u  

Explanation:

There are 3 subatomic particles present in an atom. They are: protons, electrons and neutrons.

  • Protons: They carry positive charger and are found in nucleus.
  • Electrons: They carry negative charge and are found around the nucleus.
  • Neutrons: They dos not carry any charge and are found in nucleus.

Mass of electron is almost negligible as compared to the mass of proton and neutron.

Masses of the subatomic particles:

Mass of protons = 1.007276 u

Mass of neutrons = 1.008664 u  

Mass of electrons = 0.00054858 u

Hence, average mass of proton is 1.007276 u  and that of neutron is 1.008664 u
