What is the relative atomic mass of potassium?
the relative atomic mass for the element potassium is 39.0983
What is atomic mass of carbon fourteen?
slightly more than 14, carbon 12 has an atomic mass of 12 by definition, so 1 atomic mass = the sum of the mass of a proton neutron and electron divided by 2 neutrons are slightly heavier than the combined mass of an electron and proton carbon 14 has a higher percentage neutrons than carbon 12 so it is heavier relative to the number of particles in it's nucleus(14)
What is the atomic mass of an electron?
an electron is about 1/1836 amu.
Why atomic mass is called relative atomic mass?
Atomic mass is so small you can't actually measure it. So, just like carbon dating, you have to use a relative mass.
What is the ratio of the mass proton to the mass of an ELECTRON?
Dunno, but the ratio of the mass of a proton to the mass of what prople think of as being an electron is approx 1980. I'd check that if I were you though. Probably OK to +- 5%.
Relative mass of electron?
1/1840 the mass if a hydrogen atom.
Mass of electron compared to proton?
Mass of electron is about 1837 times less than the mass of proton
What is the number of atomic mass in an atom?
Relative mass number of an electron is 0
What are the charges and relative masses of the main subatomic particles?
electron = relative charge = 1- relative mass = 1/1840 proton = relative charge = 1+ relative mass = 1 neutron = relative charge = 0 relative mass = 1
What subatomic particle Has the smallest relative mass?
In the atom the electron is the lightest.
What is the Ar of Carbon?
The Relative Mass (Ar) of carbon is 12. The Relative mass can be found very easily, it is the top number of the electron in the periodic table.
If a proton had a mass of 1 what is the mass of an electron and neutron relative to the mass of the proton?
If a proton would be 1, an electron would be 0.000544. An electron is 1,836 times lighter than a proton. A neutron would be 1.001 as a proton is 99.86% the mass of a neutron
How do you find the relative uncertainty in the mass of the electron?
The mass of the electron is 9,109 383 56(11)×10e-31 kg.The uncertainty is +/-11 for the last two decimals.
What have almost equal masses to the proton?
No, it isn't. The mass of an electron is significantly smaller than that of a proton.The mass of 1,800 electrons is about the same as the mass of one single proton.The antiparticle of the electron, the positron, has the same mass as the electron.the mass of the electron is not the same to the mass of the proton
What are Atoms 3 particles?
Proton - Relative Atomic Mass of 1, charge of 1. Neutron - Relative atomic mass of 1, charge of 0. Electron - Negligible mass (0), charge of -1.
What are the relative atomic mass of subatomic particles in atom?
neutrons are heavier than protons by a bit more than the mass of electron.
What has the least mass - electron neutron proton nucleus?
LEAST mass? That would be photos or neutrinos, which have no mass at all. Where Least is greater than zero? Electrons, probably; an electron is 1/1836th of a proton, I seem to recall. Neutrinos actually have a small nonzero mass, so small it has yet to be determined. No neutrino has a mass of more than a few eV, the electron has a mass of about 0.5MeV.
