The Electrons that revolve in shells around the nucleus have a + or - Charge? Negative Charge.
What radiation category do the x-rays belong to? Electromagnetic radiations.
What is an x-ray photon? A samll bundle of pure energy with wave-like properties.
How are x-rays produced in the x-ray tube? High speed electons interacting with the nucleus of the target atoms giving off radiation.
