Question

electron is present in the atoms ,how and why​

Answer 1

Answer:

All of the electrons of an atom create a negative charge that balances the positive charge of the protons in the atomic nucleus. Electrons are extremely small compared to all of the other parts of the atom. The mass of an electron is almost 1,000 times smaller than the mass of a proton.

Answer 2

Electron revolves around the nucleus of the atom through elliptical path called orbit and their presence is necessary because protons I.e. the positive charge is present inside the nucleus of atom so to neutralise the charge of the atom these electrons are required.
