What is equal to the mass of a proton?

already exists.

Would you like to merge this question into it?

already exists as an alternate of this question.

Would you like to make it the primary and merge this question into it?

exists and is an alternate of .

The neutron has about the same mass as the proton, each has a mass a tiny amount greater than 1 AMU (atomic mass unit). The neutron is the smallest bit more massive.

The electron has a mass of just a bit over 5/10,000ths of an AMU. Extremely less massive in comparison, isn't it!

How does the mass of an electron compare to that of a proton?

The mass of a proton is 2000 times the mass of an electron. Mass of electron: 9.10938 * 10 -31 kg Mass of proton: 1.67262 * 10 -27 kg Mass of neutron: 1.67493 * 10 -27 kg Note that protons and neutrons weigh approximately the same (neutrons are slightly heavier), but electrons are MUCH (MORE)

Is the mass number of an atom equal to the number of protons it contains?

No. The mass number (also, nucleonic or atomic number) of an atom is equal to the total number of nucleons (the collective term for protons and neutrons) in its nucleus. Isotopes are chemically near-identical atoms of an element that have the same number of protons and electrons, but a dif (MORE)

Is the mass of an electron about equal to the mass of a proton?

No, it isn't. The mass of an electron is significantly smaller thanthat of a proton. The mass of 1,800 electrons is about the same as the mass of onesingle proton. The antiparticle of the electron, the positron, has the same massas the electron. the mass of the electron is not the same to the mass (MORE)

How many electrons equal the mass of one Proton?

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 the mass of 1 proton.

How does the mass of a proton compare to the mass of a neutron?

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/c 2 . The equivalent energy of a neutron is 939.565378 MeV/c 2 . The difference is 1.293332 MeV/c 2 , which is the amount of (MORE)

Do protons and electrons equal the atomic mass?

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 the mass of an electron is, in comparison, very small.

A proton has a mass of?

A proton has what is known as one atomic mass unit (AMU) neutrons also weigh this much but electrons weigh much much less.

Who has the smallest mass protons or neutrons?

Protons have slightly less mass than Neutrons, and by slightly, it is a difference of 2x10 -24 kg, ie, 24 zeroes after the decimal point. The difference is so miniscule, that they are considered to weigh the same for most intents and purposes.

What is the mass or protons and neutrons?

Protons: 1.672621777(74)×10 −27 kg 938.272046(21) MeV/ c 2 1.007276466812(90) u Neutrons: 1.674927351(74)×10 −27 kg 939.565378(21) MeV/ c 2 1.00866491600(43) u Yes, taken from Wikipedia, for I have no idea how to write it. Sorry, Can't translate it into Human, simply b (MORE)

What is the atomic mass of an element equal to atomic number or number of protons?

Answer : The atomic mass is NOT equal to both 'atomic number' and 'number of protons . The atomic mass of an element is by approximation equal to, but not exactly , the sum of protons and neutrons in the nucleus of the atom. The number of protons is given by the atomic number, not (MORE)

Where is the location of the mass of a proton?

If the mass within a proton has any structure -- in other words, if it is NOT simply a uniform sphere of about .87 fento-meters -- at present we lack the capability to discern that structure. The mass MIGHT be concentrated in the center, or at the edge, or clumped half-way in-between. We can't know (MORE)

Is atomic mass equal the number of protons and neutrons or the weight of the nuclei?

The atomic mass number , which is always an integer, is the sum of the numbers of protons and neutrons in the nucleus. This is approximately equal to the mass of in atomic mass units of an atom of a particular isotope, because the only other constituents of an atom are electrons, of which there are (MORE)

Do protons and neutrons have equally mass?

No, although their masses are very close. The difference is noticed when one considers the internal structure of the particles: a proton is comprised of two up quarks and one down quark, whereas the neutron is comprised of two down quarks and one up quark.

Is the mass of a proton half the mass of a electron?

The mass of a Proton is certainly not half the mass of an Electron. A Proton's mass is a lot more than an Electrons. A Protons mass is around 908 MeV/c 2 , whilst an Electrons mass is 0.511 MeV/c 2 . This should answer the Question.

Which more mass a- proton or electron?

A Proton is made up of Subatomic Particles, these include Quarks and Leptons. Within a Proton are two Up quarks and one Down quark. An Up quark has a mass of 2.4 MeV/c 2 , whilst a Down quark has a mass of 4.8 MeV/c 2 . An Electron is a type of Lepton, so we can not break it down any further. An Ele (MORE)

What the mass of a proton of a mole of sodium?

What is the mass of a proton travelling at v equals 0.8c?

First compute the Lorentz factor gamma. v/c = 0.8 v^2/c^2 = .64 1 - v^2/c^2 = 0.36 √(1 - v^2/c^2) = √.36 = 0.6 gamma = √(1 - v^2/c^2) = 1/0.6 = 1.6667 This is the factor by which the proton gains mass. So the answer is 1.667 x rest-mass Look up rest mass of proton & mu (MORE)

Is the mass of the proton about one atomic mass?

No. Different elements have different atomic masses, the allprotons have the same mass (ignoring the small mass loss to bindingenergy when bound inside an atomic nucleus). The atomic mass of an element is the weighted average of the atomicmasses of all isotopes of that element. The atomic mass of an (MORE)
