The alpha, α – particles possess following 10 properties:
1. Alpha, α – particle carries double the positive charge of proton, which is equal to the charge on the helium nucleus.
2. Mass of an alpha, α – particle is roughly four times that of hydrogen atom i.e. it is equal to the mass of the helium nucleus.
The above two properties establish that an alpha, α – particle is equivalent to helium nucleus (or a helium atom which has lost its two orbital electrons i.e. a doubly ionized helium atom). Continue reading “10 properties of alpha particles”
