Compared with an atom. Protons and neutrons make up the nucleus of an atom with electrons in energy levels round the outside. If a proton has a mass of 1, then a neutron has a mass of very nearly the same (1) but an electron has a mass of 1/1836 or nearly two thousandth the mass of a proton.

What is compared to the electron that has very little mass?
Electrons are compared to Dynes....thx
What does the cloud around the atom's nucleus contain?
Electrons, small negatively charged particles with very little mass compared to that of the nucleus.
The electron has very little mass compared to the blank or blank fill in the blank please Number Standard Neutrons Protons Mass?
The electron has very little mass compared to the proton or neutron.
Why does the number of electrons have little effect on the overal mass of an atom?
Electrons are very light. Protons are approx. 1800 X the mass (rest mass to be presice). Neutrons are about the same mass a protons. So the mass of all the electrons has little effect.
What Mars has very little?
There are probably several things Mercury has very little of, but compared to the other planets is has very little size/mass and very little distance from the sun.

Which contains a little mass out of the atoms three components?
Protons and Neutrons have almost equal mass. However, electrons mass is very less as compared to them.

Why doesnt the mass number change when electrons are added or removed?
The mass of an electron is very small, almost negligible, compared to that of a proton or neutron.
Is the number of electrons the same thing as the atomic mass in an atom?
No, electron count really doesn't have anything much to do with atomic mass. Let's look. Most of the mass of any atom is concentrated in the nucleus. It's the protons and neutrons there that give the atom "weight" and the electrons contribute almost nothing. Additionally, electrons can be loaned or borrowed by atoms, and this changes their mass very little. The number of electrons is not very "connected" to atomic mass of an atom.
Who discovered that an electron has a mass that is very small compared to the size of the atom?
Since electrons were particles, it was obvious that they had some mass.Ever since electrons were discovered, there was curiosity to find the magnitude of their charge and mass. Millikan performed the famous oil-drop experiment and found out the charge of electrons .After that he equated it with the charge to mass ratio of electron and found out the mas of the electron.
Why an electron is ignored from the calculations of the weight of an atom?
The mass of a proton is about 1.67 * 10−27 kg or 1.007 atomic mass units. Neutrons are very close to this, at 1.675 *10-27 kg, or 1.009 atomic mass units. Electrons have a mass less than approximately 1/1836 of this so can effectively be ignored.
Which subatomic particles have very little mass and a negative charge-?
You're probably thinking of electrons, whose mass is much smaller than nucleons but also have a negative charge. Indeed, the electron has the smallest amount of mass of any particle with a negative charge.
Are protons small or big?
protons are very very tiny but compared to electrons they are big
