The mass of a proton is about 1.672621777 x 10-27 kg.
The mass of a neutron is about 1.674927351 x 10-27 kg.
The equivalent energy of a proton is 938.272046 MeV/c2.
The equivalent energy of a neutron is 939.565378 MeV/c2.
The difference is 1.293332 MeV/c2, which is the amount of energy released when a down quark is converted into an up quark, changing the neutron into a proton during beta- decay, releasing an electron (0.510998928 MeV/c2) and an electron antineutrino (< 2.2 eV) plus energy of about 0.782333 MeV/c2.

Neutron: 1,008 664 915 6 (6) atomic mass units (u)
Electron: 5,485 799 094 3(23).10-4 atomic mass units (u)
If you set the mass of an electron as 1
Then the mass of a proton is 1835 (Approx)
The mass of a neutron is 1836 (Approx)
The mass of a proton is 1.672 621 777 (74) x 10-27 kg.
The mass of a neutron is 1.674 927 351 (74) x 10-27 kg.
The mass of an electron is 9,109 382 91 (40) x 10-31 kg.
The ratio mass of the proton/mass of the electron is 1836.
A neutron has slightly more mass than a proton.
Neutrons are very slightly more but almost the same mass as a proton, while electrons are 1,830 times less massive.
If we give them relative numbers, the proton has a mass of 1.0073, the neutron has 1.0087 and the electron has 5.486 X 10 to negative 4.
The ratio mass of proton/mass of electron is 1836.
The atomic masses of two isotopes of cobalt are 59 and 60. What is the number of protons in each?
The atomic mass unit is defined to be 1/12 of the mass of a carbon-12 atom. Atomic masses can determined by weighing molar amount of an isotope. Absolute masses (in kg) are determined by measuring the amount that charged atoms are deflected by magnets, since if you know the charge you can calculate mass from the amount of deflection.
negative protons are positively charged neutrons are neutral electrons are negative the masses of neutrons and protons are approximately equal and electrons, which "orbit" around the nucleus (the protons and neutrons) are much smaller mass-wise protons and electrons charges are equal and opposite
Cl-37 : 17 protons , 20 neutrons , 17 electrons Compare with Cl-35 ; 17 protons , 18 neutrons, 17 electrons. These are two different and common isotopes of chlorine. Remember 'Different isotopes have a different number of neutrons'. Chemically they react the same.
Two atoms are considered different isotopes of their element if they have different masses. This mass comes from the neutral-charged neutrons differing.
mass of electron = 1/1836 mass of proton (or neutron)
Isotopes involve different atomic masses. It is sum of number of protons and neutrons.
the atomic mass is determined by adding the weight of protons & neutrons
The total number of protons plus the total number of neutrons
protons and neutrons are about 1 amu
protons and neutrons
Protons and neutrons.
The atomic nucleus contains neutrons and protons (apart from hydrogen-1 which only has 1 proton and no neutrons). The difference between them is that protons have a positive charge and neutrons have no charge. They also have slightly different masses.

No, Protons and Neutrons have similar masses, but one electron is equal 1/1836 of a proton in mass.
the number of protons and neutrons in an atom. Atomic mass is found by adding together the individual masses of the numbers of protons, neutrons, and electrons in the atom. --> Atomic Mass = protons + neutrons
The sum of masses of protons, neutrons and electrons.
