Solution

Protons:-

  • Protons are nothing but the subatomic particles which positively charged and that are present in the nucleus of an atom.
  • They are represented by the symbol p.
  • They have a charge of +1.602×10-19coulomb
  • They have a mass of 1.67×10-27kg

Electrons:-

  • Electrons are the subatomic particles which are negatively charged, that is they carry a negative charge.
  • They revolve around the nucleus of an atom and have the same charge as that of a proton but opposite in sign.
  • They are represented by the symbol e-.
  • They have a charge of -1.602×10-19coulomb
  • They have a mass of 9.10×10-31kg

Atom with one electron and one proton:-

  • We already have known that an electron has an opposite charge to that of a proton.
  • And also the magnitude of the charge is equal.
  • As a result if the atoms have 1 electron and 1 proton, then that atom will be electrically neutral.
  • This means that the atoms will carry no charge as their neutral.

Therefore, if an atom contains one electron and one proton, will it carry no charge.
