Question

Why charge on alpha particle is +2e?

Open in App

Solution

Mass of alpha particle = 4 * mass of proton. Charge on alpha particle = 2 *charge on proton. Positively charged particle emitted by various radioactive materials during decay. ... An Alpha particle is a Helium nucleus consisting of two protons and two neutrons so itscharge is +2e
