Estimate the percentage of the total mass of a 58Ni atom that is due to (a) electrons, (b) protons, and (c) neutrons by assuming that the mass of the atom is simply the sum of the masses of the appropriate numbers of subatomic particles. The mass of an electron is 0.00054858 amu, the mass of a proton is 1.0073 amu, and the mass of a neutron is 1.0087 amu. a. % by mass e- b, % by mass p c.90 by mass n- 0 0 0 0
Ni-58 has 28 electrons, 28 protons and 30 neutrons in it
Calculate total mass of Ni-58
mass of electrons = 28 x 0.00054858 amu = 0.01536 amu
mass of protons = 28 x 1.0073 amu = 28.2044 amu
