.. attraction between the lone and proton in a hydrogen atom". But what is
a lone? A hydrogen atom has one electron and one proton. So, by lone you mean
perhaps the electron.
An electron is the smallest negative charge while a proton is the smallest positive
charge. The charge of an electron is -1.6 × 10⁻¹⁹ coulomb(C) while the charge of a
proton is +1.6 × 10⁻¹⁹ C. To compute the force between two charges, use the formula
for the Coulomb force ... F = kQ₁Q₂ / r ² ... where k = 9 × 10⁹ N • m² / C² = constant.
Using Q₁ for the charge of the electron and Q₂ for the charge of the proton, we get
... F = ( 9 × 10⁹ N • m² / C² ) ( -1.6 × 10⁻¹⁹ C ) ( +1.6 × 10⁻¹⁹ C ) / ( 8.2 × 10⁻¹¹ m )²
…... = -3.43 × 10⁻⁸ N
for the magnitude of the force of attraction between the electron and the proton in a
hydrogen atom. The negative sign in the force denotes attraction.
