Is an alpha particle an electron
Web7 jul. 2024 · An alpha particle is identical to a helium atom that has been stripped of its two electrons; thus, an alpha particle contains two protons and two neutrons. Because an alpha particle has no electrons to balance the positive charge of the two protons, it has a charge of +2 and can be represented as He 2+. WebA proton and electron have the same kinetic energy, let's compare their de Broglie wavelength. Next, a proton, and an alpha particle are accelerated through the same …
