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.

The atomic masses of two isotopes of cobalt are 59 and 60 what is the number of protons and neutrons in each?
The atomic masses of two isotopes of cobalt are 59 and 60. What is the number of protons in each?
Which particles determine the mass of an atom?
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.
If someone picks up an excess of electrons while walking across a carpet their charge would be?
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
What occurs for two atoms to be isotopes of each other?
Two atoms are considered different isotopes of their element if they have different masses. This mass comes from the neutral-charged neutrons differing.
How many protons neutrons and electrons are in chlorine 37?
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.
How do the masses of one electron compare to the masses of protons and neutrons?
mass of electron = 1/1836 mass of proton (or neutron)
Is the is the sum of the numbers of protons and neutrons in an isotope of the element?
Isotopes involve different atomic masses. It is sum of number of protons and neutrons.
Atomic mass of an atom is determined by the combined masses of?
the atomic mass is determined by adding the weight of protons & neutrons
The atomic mass of an atom is determined by the combined masses of its what?
The total number of protons plus the total number of neutrons
What are the masses of each subatomic particle?
protons and neutrons are about 1 amu
What are atoms of an element that make different atomic masses?
protons and neutrons
What The atomic mass of an atom equals the sum of the masses of the?
Protons and neutrons.
What do neutrons and protons have common?
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.
What neutrons and protons have in common?
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.
Do electrons neutrons and protons have essentially the same mas?
No, Protons and Neutrons have similar masses, but one electron is equal 1/1836 of a proton in mass.
What information does the atomic mass of an elemt provide?
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
What is the mass of an atom mainly determined by?
The sum of masses of protons, neutrons and electrons.
