Question

Compare an electron, a proton and a neutron in respect of their relative masses and charges.

Answer 1

Protons and neutrons have approximately the same mass, but they are both much more massive than electrons (approximately 2,000 times as massive as an electron). The positive charge on a proton is equal in magnitude to the negative charge on an electron.

Answer 2

Neutrons have No Charge

Explanation:

• Electrons (- Charge)

Mass of Electron = $9 \times 10^{-31}\ kg\ (\frac{1}{1840}\ of\ H)$

Charge is $1.6 \times 10^{-19}$ Coulombs

• Proton (+ Charge)

Mass of Protron = $1.67 \times 10^{-27}$ kg or 1 u  

Charge is $+ 1.6 \times 10^{-19$} Coulombs

• Neutrons ( No Charge)

Mass of Neutron = 1 u or $1.67 \times 10^{-27}$ kg

Charge - No Charge
