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.

What contributes the most volume of an atom nuclear or electron cloud?
The electron cloud contributes the most volume of an atom. While the nucleus contains most of the atom's mass, it occupies a very small space compared to the vast area of the electron cloud, where electrons are found. The electron cloud's size is determined by the energy levels and orbitals of the electrons, making it the dominant contributor to the overall volume of an atom.
What did Rutherford discover about the volume of the nucleus?
Rutherford discovered that the nucleus occupies a very small volume compared to the overall size of the atom. He found that the nucleus is extremely dense and contains nearly all the mass of the atom, while the rest of the atom is mostly empty space.
What is most of the volume of an atom taken up by?
Most of the volume of an atom is taken up by the electron cloud, which consists of electrons moving around the nucleus. The nucleus, which contains protons and neutrons, is extremely small compared to the overall size of the atom.
How big are the parts of the atom compared to the whole atom?
The nucleus of an atom is very small compared to the size of the whole atom. The nucleus makes up only a tiny fraction of the atom's total volume, while the rest of the atom (which is mostly empty space) is occupied by the electron cloud.
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.
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 is the lightest subatomic particle of an atom?
electrons the smallest but weigh as much as protons neutrons weigh nothing ~Kay
Which subatomic particle is very small?
Proton is a positive particle and electron is a negative particle.
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.
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.
How big are the parts of the atom compared to the whole atom?
The nucleus of an atom is very small compared to the size of the whole atom. The nucleus makes up only a tiny fraction of the atom's total volume, while the rest of the atom (which is mostly empty space) is occupied by the electron cloud.
What did Joseph John Thomson conclude about the atom?
J.J. Thomson discovered the electron and proposed the plum-pudding model for the atom.
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.
When a neutral atom loses an electron what happens to its size?
When a neutral atom loses an electron, it becomes a positive ion. The loss of an electron reduces the electron-electron repulsion, causing the remaining electrons to be more strongly attracted to the nucleus. This contraction in electron cloud typically results in a smaller ionic size compared to the neutral atom.
