Hint:Electron is a subatomic particle whose electric charge is negative one elementary charge. All of the electrons in the atoms creates the total negative charge that balances the total positive charge of the atom.
Complete step-by-step answer:
We know that the magnitude of charge on an electron in coulombs is negative of
As the Electron is a negatively charged subatomic particle whose mass is
The mass of the electron is 1000 times smaller than the mass of proton which is the positively charged subatomic particle of the same amount .
Elementary charge is the fundamental electric charge which is constant and it is carried by proton and electron provided protons charge is and electrons charge is .
Hence, option (B) “ ” is the correct option.
Additional Information:
An atom is made up of protons, neutrons, and electrons, although protons and neutrons are further divided into quarks.
The nucleus is the center of an atom in which neutrons and protons reside, as neutrons are neutral particles so the nucleus is positively charged due to protons.
Collectively, neutrons and protons are known as Nucleons.
Electrons are said to revolve around the nucleus in fixed orbits which are decided according to Bohr’s quantum model.
Atom as a whole is electrically neutral, that is it has no charge because the total number of protons and electrons are equal in it.
Note:
Unlike protons and neutrons which can be further made up of three quarks, the electron is an elementary particle, which means it cannot be further divided.
The particles that are responsible for making up an atom are known as the elementary particles.
