Question

What is the absolute mass and charge of a proton?

Answer 1

• The mass of protons is similar to the mass of a hydrogen atom.
• As one hydrogen atom consists of a proton and an electron and we know that mass of an electron is negligible. So, mass of hydrogen atom is equivalent to the mass of a proton.
• Mass of Proton = $1.676\times {10}^{-27}kgor1.676\times {10}^{-24}g$.
• Protons are positively charged, they have an equal but opposite charge to that of the electron.
• Charge of a proton =$+1.602\times {10}^{-19}$Coulomb
• Therefore, the absolute mass of proton=$1.6\times {10}^{-27}kg$ and absolute charge of the proton is $1.602\times {10}^{-19}$coulomb.
