Why does the neutron have the most mass in an atom?
Yes, a neutron has more mass than a proton or electron.
Is a neutron heavier than an electron?
A neutron is actually heavier than a proton because a neutron is made up of a proton + an electron + subatomic particles. The relative masses are: * Mass of neutron: 1,6749 x 10^(-27) kg * Mass of proton : 1,6726 x 10^(-27) kg * Mass of electron: 0,00091x10^(-27) kg
Would a electron have far less mass than a proton or a neutron?
Yes, the mass of an electron is roughly 1835 times less
Do protons and neutrons have nearly the same mass?
No, the proton and neutron don't have the same mass. A neutron is about 1.00138 times as heavy as a proton. The neutron is just a bit bigger, as you can see, and when a free neutron decays, it releases a proton and an electron. It might be said that a proton plus an electron equals a neutron, but you might not be able to get a physicist to say that. Links can be found below for more information.
Do electrons have any mass?
Yes, electrons have a mass, as everything has mass. However, an electron's mass is so small that it is considered to be 0.
How does the mass of an electron compare to the mass of a whole atom?
yes the mass of an electron is much tinnier fraction of the mass of an atom
In beta Decay a neutron is converted into a proton and what?
In beta decay, the nucleus of the atom emits an electron. This is a new electron, not one of the electrons in the electron cloud. This does indeed have the effect of changing a neutron into a proton, because total charge has to be conserved - if a new negative thing exists, there has to be a new positive thing too. But the mass has to stay the same too - conveniently, protons and neutrons have almost the same mass.
Is a electron smaller than a neutron?
No, protons and neutrons are in the nucleus and the electrons orbit around the nucleus. This all happens inside the atom.
All protons have the same mass?
They are very close but the neutron has slightly greater mass. The masses are as follows: Proton: 1,6726 X 10-27 kg Neutron: 1,6749 X 10-27 kg The proton is about .13% smaller than the neutron Another good way to think about it is that the masses equate this way: Mass of 1 Proton + Mass of 1 electron approximately = Mass of 1 neutron See the related links for further information.
Is Most of the mass of an atom is in the nucleus?
Because proton and neutron are in about one thousand times heavier than electron.
How does the mass of a proton compare to a neutron?
Yes, in general. All hydrogen atoms contain one proton, most with no neutrons and all neutral atoms with one electron - and the electron has a much smaller mass. Some hydrogen atoms contain one (or, rarely, two) neutrons and so are heavier. But on average the atom has a mass much the same as a proton.
Does electron mean a subatomic particle with a negative charge?
Electrons are negatively charged subatomic particles, but have almost no mass. The mass of an electron is about 1/2000 that of a proton or neutron. The neutron is the most massive of the subatomic particles at 1.6755 x 10-24 grams.
