alpha particles contain two protons and two neutrons-identical to a helium atom. alpha particles do not initially have electrons, but they will take them from their environment in the jar.
The nucleus of a helium atom is called an alpha particle. The electromagnetic waves emitted by a nucleus are called gamma rays.
Alpha is a particle not a wave. Alpha particle are positively charged helium nuclei and have a +2 charge and 4u mass.
The radioactive alpha particle has the same structure as the atomic nucleus of helium. They are usually formed and emitted during alpha decay.
A helium nucleus (2 protons & 2 neutrons).
An alpha particle is a helium nucleus; it has a charge of +2.
An alpha particle is equivalent to a helium-4 nucleus, or a helium-4 ion. A difference is that an alpha particle has a certain amount of energy associated with it, so it can said to be fast or hot. The energy is measured in thousands or millions of electron volts (keV or MeV).
The nucleus of a helium atom is called an alpha particle. The electromagnetic waves emitted by a nucleus are called gamma rays.
Curium is a strong alpha particle emitter and can be used as alpha particle source or in isotopic heat generators.
Because an alpha particle is bigger than a helium or hydrogen atom.
An alpha particle is identical to the nucleus of Helium atom
