Which statement best describes gamma radiation?
(1) It has a mass of 1 and a charge of 1.
(2) It has a mass of 0 and a charge of –1.
(3) It has a mass of 0 and a charge of 0.
(4) It has a mass of 4 and a charge of +2.
The correct answer is option 3. The gamma radiation has no mass and no charge. This is produced from the release of pure energy from the nucleus. This is simply a stream of high frequency energy.
