Question

If an atom contains one electron and one proton, will it carry any charge or not?

Answer 1

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 $\mathrm{p}$.
• They have a charge of $+1.602\times {10}^{-19}\mathrm{coulomb}$
• They have a mass of $1.67\times {10}^{-27}\mathrm{kg}$

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 ${\mathrm{e}}^{-}$.
• They have a charge of $-1.602\times {10}^{-19}\mathrm{coulomb}$
• They have a mass of $9.10\times {10}^{-31}\mathrm{kg}$

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.
