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.

When compared with the energy of an electron in th first shell of a carbon atom the energy of an electron in the second shell of a carbon atom is?
greater
How is the size of an anion different from the size of the atom from which it was formed?
Anion will have more electron than which atom it was form. So, after forming the the atom will have more electron cloud and size will be smaller compare to the original one.
Who discovered small negatively charged particles inside an atom?
J.J Thomson
What is the size of an atom versus an electron?
an atom is larger than an electron
What happens when an electron is added to an atom it will acquire?
when an electron is added to an atom, the atom will acquire a negative charge.
When compared with the energy of an electron in th first shell of a carbon atom the energy of an electron in the second shell of a carbon atom is?
greater
Is an electron bigger then an atom?
No. An electron as a particle is small however the probability cloud of an electron can be large- most of the volume of an atom consists of the electron cloud. In relation to this the nucleus, although it contains nearly all of the mass of the atom, is quite small.
What are found in the space surrounding the nucleus of an atom?
The space around the nucleus of an atom is called the electron cloud. The electron cloud is the space in which the electrons of that atom travel. Compared to the nucleus, the electron cloud is enormous.
Which subatomic particle is very small?
Proton is a positive particle and electron is a negative particle.
How is the size of an anion different from the size of the atom from which it was formed?
Anion will have more electron than which atom it was form. So, after forming the the atom will have more electron cloud and size will be smaller compare to the original one.
What did Sir Ernest Rutherford invent?
Ernest Rutherford discovered that the nucleus of an atom has a positive charge and discovered the evidence to show the electron field surrounding the nucleus in an atom.
What did Joseph John Thomson conclude about the atom?
J.J. Thomson discovered the electron and proposed the plum-pudding model for the atom.
What is an electron in an atom?
Electron is a negatively (-) charged particle found in a atom. Unlike proton and neutron, electron is found in orbital shells of atom, but not in nucleus. Electron are very small that is why they don't contribute to the atomic mass of a element. Electron are responsible for forming ions and take part in chemical reaction.
What was the first part of the atom to be discovered?
Its the electron! There short and sweet! Its the electron! There short and sweet!
Physicist and their contribution?
Rutherford. Discovered small charged nucleus of atom. Split the atom.
This part of an atom carries a negative charge?
This is made up of protons and neutrons, this part of the atom contains nearly all the mass. This small particle of an atom that carries a negative charge.
Is a twizzler a large or small mass?
It depends on the context. Compared to an atom it is huge, compared to the sun it is tiny.
