1836 times the mass of an electron So how do you calculate '1836 times the mass of a proton' ? Mass of proton = 1.673 x 10-27 or (10 to the power of negative 27) Mass of… electron = 9.109 x 10-31 or (10 to the power of negative 31) Simply by dividing the largest mass (of protons) by the smallest mass (electrons): (1.67262 . 10-27) / (9.10939 . 10-31) = [1.67262 / 9.10939] . [10(-27)-(-31)] = 0.1836 . 10+4 = 1836
electron mass = 0.0005446623 amu = 9.1093 × 10-31 kg proton mass = 1.0072764668amu = 1.6726 x 10-27 kg neutron mass = 1.0086649156 amu = 1.6749 x 10-27 kg
it is the sum of the number of neutrons and protons Mass number is the sum of number of neutrons and protons while atomic number is equal to number of protons or electron…s..
It would take about 333,000 earths to match the mass of the sun.
How many moons would it take to equal the mass f earth? I am going to assume you are referring the Earth's moon. This is a rather simple calculation. We simply take the ma…ss of the Earth, and divide by the mass of the moon. We can express the formula like this. mass of moon * number of moons = mass of Earth therefore mass of Earth ÷ mass of moon = number of moons The mass of the moon is approx. 7.347 7 × 1022 kg. The mass of the Earth is 5.9736×1024 kg. Now, it is a simple matter of division, and we can get the number 81.30081 recurring, so lets just say 81.3.
1836 electrons equal the mass of 1 proton. A proton has a mass of 1.0073 amu, a neutron 1.0087 amu, and an electron 5.486 x 10-4. So, it would take 1836 electrons to equal t…he mass of 1 proton.
no just protons + neutrons but always number of electrons= number of protons( in an atom)
Protons and neutrons equal atomic mass. Although an atom has the same amount of protons as electrons, saying that electrons + neutrons = atomic mass would be incorrect as th…e mass of an electron is, in comparison, very small.
They are opposite in charge. Protons have a positive charge and electrons have a negative charge. The mass of a proton is 1838 times that of an electron. Mass of electron: 9….10939 x 10-31 kg Mass of proton: 1.67262 x 10-27 kg
No, there are the same number of protons and electrons in an atom, but I don't think that they have the same mass. You're right, an electron is 1,836 times lighter than a pr…oton.
How many protons electrons and neutrons would be found in neutral carbon isotope with an atomic mass of 14amu?
6 protons [because Carbon is number 6] 6 electrons [because if you want it to be neutral it has to be same as protons number] 8 neutrons [because atomic mass contains neut…rons + protons. 14 - 6 = 8]
In a way yes, it is really only the amount of protons and neutrons, but electrons are so small they carry so little weight that they add so little consequece to the atomic wei…ght of an atom.
It would become unstable and would go through beta decay to reach a stable amount of protons to neutrons.
