have, not has, and I would assume that it has electrons to be electromagnetic radiation, and therefore mass
No.
E = mc2
RADIATION
Mass spectrometry doesn't use electromagnetic radiation, hence why it is not called Mass spectroscopy. Instead Mass spectrometry uses high energy electrons to ionize the sample molecules, which helps determine the mass of the molecules and any fragmented ions from the parent ion.
This is a positron.
The gamma particle's symbol is the lowercase Greek gamma, the velar, which looks like a lower case western v, but the base has a narrow loop, and the left top has a curved serif. In print, it looks like a Y, shifted down as if it were a lower case letter with a descender. We can't represent it here on Answers.com, but the Related Link below will take you to WikiPedia where you can see a representation of it. The charge of a gamma particle is that of the photon, which is zero.
No Gamma Rays do not have mass. All electromagnetic radiation has no mass.
Free radiation I suppose. But gamma radiation, is charge free. As is UV, IR, ... ..
All electromagnetic radiation lacks mass. We sometimes use the term photon to refer to light, which is a form of electromagnetic energy. Light has no mass. None.
No, gamma rays are electromagnetic radiation which has no charge.
an energy ray with no mass and no charge
Electromagnetic radiation can behave either as a wave or a particle. A wave particle is duality. Electromagnetic energy results from acceleration of a charge EM radiation can travel through a medium or vacuum.

Gamma radiation
Photons or electromagnetic radiation.
They are electromagnetic radiation, so no.
Photon
