The nucleus of the oxygen atom contains 8 protons and 8 neutrons. How many times is the mass of all nucleons in an oxygen atom greater than the mass of all electrons? In calculations, assume that the mass of an electron is 1/2000 of the mass of a nucleon.

The nucleus of the oxygen atom contains 8 protons and 8 neutrons. Atom is an electrically neutral particle, so the number of electrons in it coincides with the number of protons.

The masses of nucleons (protons and neutrons) are practically equal to each other.

Let the mass of the nucleon be x, then the mass of the electron is 1/2000 x.

m (nucleons) = 8x + 8x = 16x

m (electrons) = 8x / 2000 = 0.004x

m (nucleons) / m (electrons) = 16x / 0.004x = 4000

Answer: in an oxygen atom, the mass of all nucleons is 4000 times greater than the mass of electrons. How many times in an oxygen atom is the mass of all nucleons greater than the mass of all electrons? In calculations, assume that the mass of an electron is 1/2000 of the mass of a nucleon.
