SUMMARY
The mass of a hydrogen atom (H) is approximately 1.673 x 10^-27 kg, which is equivalent to the mass of a proton. While the mass of the electron is significantly smaller—about 1/2000th that of a proton—its inclusion in precise calculations can be considered negligible for most practical purposes. Therefore, for general discussions and calculations, the mass of the hydrogen atom can be effectively represented by the mass of the proton alone.
