What else can I help you with?
What part of an atom has the least mass?
the electron is the least massive atomic particleelectron
What is an uneven distribution of charged in an atom?
Proton: positive charged Electron: negative charged Neutron: neutral
Protons are so much more massive than electrons that you can neglect the mass of electrons when determining the mass of an atom?
Atomic mass is based on the proton and neutron. For the most part the mass of an electron is infinitesimally small.
What are the weights of the subatomic particles?
I think you probably mean the mass of the classical subatomic particles, Proton, Neutron and Electron. From memory, the mass of the proton and neutron are almost the same and approximately 1.6 x 10-24 grams while the mass of an electron is about 0.9 x 10-28 grams. In the Standard Model of subatomic particles, there are very many more particles than these three and their masses are best looked up in tables. Some of the masses of subatomic particles have not yet been determined (neutrinos) and one of the theoretical particles has not yet been shown to exist at this time (Higgs boson).
List three main particles of an atom and explain how they differ from one another?
Protons and neutrons are found in the atom's nucleus and represent practically all of an atom's mass. Protons are positively charged, while neutrons are neutral. Electrons orbit the nucleus in regions called energy levels (or shells) and carry a negative charge.
Does an electron have more maas than a proton or neutron?
an electron is much lighter than a proton or neutron.
Why does the neutron have the most mass in an atom?
Yes, a neutron has more mass than a proton or electron.
What has a mass slightly less than that of a neutron?
A proton has a mass slightly less than that of a neutron. A neutron is slightly more massive due to the extra mass of an additional electron.
Has no charge and weighs slightly more than a proton?
The neutron has no charge and weighs slightly more than a proton. It is a subatomic particle found in the nucleus of an atom along with protons.
Does electron weigh more or less then proton and neutron?
Protons are made up of Subatomic Particles, in this case a Proton Atom is made up of two Up quarks, and one Down quark. The mass of an Up Quark is 2.4 MeV/c2 and the mass of a Down quark is 4.8 MeV/c2. Electrons are still in the Subatomic Particle Table, an Electron is a type of Lepton. An Electron's mass 0.511 MeV/c2 which is a lot less than a Proton, even less than a Up quark itself (the lightest quark). In most cases when talking about Atoms and their mass Electrons don't normally have an effect on their mass, only the Neutrons and Protons in the Atom. This should answer the Question.
Is the electron or the neutron or the proton lighter?
The electron, the neutron and the proton are the building blocks of the atom. And of the three, the electron is far and away the lightest. The neutron is slightly heavier than the proton, and either particle is over 1800 times more massive than our little electron.
Is the electron the largest of the three main atomic particles?
The electron is the smallest of the three main atomic particles by a long way. The proton and neutron are of a similar size, with the neutron having (very) slightly more mass. The mass of an electron is around 1/1840 of a proton or electron.
What particle has the same mass as a neutron?
A positron, a neutron, a single proton, and a single electron are all considered to be equal in mass, however, a positron is generally referred to as an "anti-electron", as it travels at the velocity of light (like an electron), an has a positive charge (+1e, as opposed to an electron, which carries a negative charge, i.e: -1e).
Which subatomic particle is nearly equal to the masses of the other two subatomic particles added together?
The neutron has a mass that is nearly equal to the combined mass of a proton and an electron. This is due to the fact that the neutron is slightly heavier than the proton, while the electron has a much smaller mass.
How does the mass of an electron compare to that of a neutron?
The nucleus is far more massive than the electron cloud. The mass of the electron cloud is almost negligible compared to that of the nucleus.
Which has least mass neutron protron electron or nucleus?
Well, that's kinda a trick question because an electron is pure energy. An electron particle is also the smallest of the 4, so its the electron (eventhough an electron is a weichtless particle such as a graviton or magneton! Hope I helped!!
Which has more mass-a proton or electron?
The proton has much more mass than the electron, by a factor of 1836 times, a ratio called "mu". Recent astronomical research suggests mu may have changed by 20 parts per million in the last 12 billion years, but I plan to wait at least a billion years for confirmation!
