* Mass: An alpha particle has a mass of approximately 4 atomic mass units (amu). This is because it consists of 2 protons and 2 neutrons.
* Charge: An alpha particle carries a +2 charge. This is because it has two protons, each with a +1 charge.
Important Note: While the mass of an alpha particle is close to 4 amu, it's not exactly 4 amu due to the binding energy of the nucleons within the particle.
