Positively charged particle consisting of 2 protons and 2 neutrons which is given off by a radioactive substance is called what?

A radiation particle consisting of two protons and two neutrons is called an Alpha Particle. Alpha Particles have the same structure as a Helium nucleus. There are three forms of radiation, Alpha (Helium nucleus), Beta (a lone electron) and Gamma (an Electromagnetic wave).


What is an alpha particle equivilent to?

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).
