Question

What are $\alpha$-particles? What are the charge and mass of $\alpha$-particles?

Answer 1

Alpha particle:

1. Alpha particles, also known as alpha rays or alpha radiation, are made up of two protons and two neutrons bonded together to form a helium-4 nucleus-like particle.
2. The charge of an $\alpha$-particle is $3.2\times {10}^{-19}\mathrm{C}$ (2 times the charge of a proton).
3. The mass of an $\alpha$-particle is $6.68\times {10}^{-27}\mathrm{kg}$ (4 times the mass of a proton).
