Alpha waves are a type of neural oscillation in the brain that occur at a frequency of 8-12 Hz. They are not particles but rather a characteristic of brain activity observed on electroencephalography (EEG) tests.
An alpha particle has a charge of +2e, where e represents the elementary charge of a proton. This means that an alpha particle has a charge equivalent to two protons.
An alpha particle has a charge of 2, which means it is positively charged.
Gamma rays are not particles, they are a form of electromagnetic radiation. Alpha and beta particles are types of particles emitted during radioactive decay.
In alpha decay, the emitted particle has a charge of 2.
The nucleus of a helium atom is called the alpha particle, which consists of two protons and two neutrons. It is positively charged and accounts for most of the mass of the helium atom.
