Gamma rays belong to the electromagnetic spectrum. In frequency and consequent energy the spectrum runs from very very long low energy radio waves up to the highest energy and frequencies which include gamma rays.
Somewhere between those very low energies and the highest energies lies the visible light frequencies and energies. You know them as ordinary light. And I suspect you've heard light consists of photons, which are massless.
I mention the visible light to point out that gamma rays belong to the same EM spectrum so they too are made of the same stuff that visible light is made of...photons. And photons have no mass; they are massless bits of energy.
In short, gamma particles, which are photons, have no mass. ANS.

∙ 9y agoSince it is a photon, its rest mass is zero. Its relativistic mass, of course, will depend on its energy. Typical gamma rays have energies over 100 keV, so their mass (their relativistic mass, that is) can be expressed as 100 keV/c².

∙ 11y agoOf course alpha is a particle nothing but the helium nucleus, beta is also a particle which is fast moving electron. But gamma is not a particle. It is electromagnetic radiation. So gamma photon. But photon has zero rest mass.

∙ 16y agothe mass of a beta particle is that of an electron which is 0.000544662309 amu (atomic mass units) or in kilograms that's 9.10938188 × 10-31 kilograms

The nuclear reaction for the emission of gamma particle from cobalt 60?
Cobalt-60m decays by emitting a gamma particle. This changes neither the atomic number nor the isotope number, since no nucleons are lost. The gamma particle has an energy of 58.59 keV. The resulting atom is Cobalt-60.
What is the particle that is same as helium nucleus out of alpha and beta and gamma?
Alpha because it has a mass of 4
What one of these is not particle proton neutron alpha gamma ray or a beta particle?
The gamma ray is not a particle but is just an EM wave that transmits energy.
What radioactive particle has the deepest penetration?
The gamma particle has the deepest penetration.
Can you use the atomic number and atomic mass to calculate the number of each subatomic particle?
atomic number = number of protons = number of electrons atomic mass = mass of protons + mass of neutrons
Nuclear radiation ranked from the greatest mass to the least mass is a- Xray gamma ray beta particle b- Xray beta particle gamma ray c- Alpha particle beta particle gamma ray d Beta alpha gamma?
aplha, beta, gamma
What is the mass number of gamma rays?
Gamma rays hasn't a mass number.
How do the mass and size of an alpha particle compare with mass and size of beta particle?
The mass and size of an alpha particle compare with the masa and size of beta particle in the sense that the alpha particle is significantly larger in both size and mass that the beta and gamma particles. This is why it is called the alpha particle.
What is gamma particle?
an energy ray with no mass and no charge
When a nucleus undergoes radioactive decay its new mass number is?
It depends. If the decay contains a particle with mass, then the nucleus' mass number must decrease. If the decay involves the emission of a massless particle (like a gamma photon), then the mass number is unchanged. If the reaction (not technically a decay) involves the nucleus absorbing a particle with mass (like U-235 absorbing a neutron in a fission chain reaction) then it is a transmutation and not a natural decay. The mass number must increase.
What are the masses of alpha beta gamma?
The alpha particle basically has the mass of a helium atom, since it is a helium nucleus. The beta particle has the mass of an electron - a beta particle is either an electron or an anti-electron. The gamma ray has no rest mass, since it moves at the speed of light. However, it can have a fairly high energy, and therefore an associated mass. The mass varies in this case; that is, gamma rays can have different energies, and therefore different masses.

Cobalt-60m decays by emitting a gamma particle. This changes neither the atomic number nor the isotope number, since no nucleons are lost. The gamma particle has an energy of 58.59 keV. The resulting atom is Cobalt-60.
What is the particle that is same as helium nucleus out of alpha and beta and gamma?
Alpha because it has a mass of 4
Which has the largest mass alpha particle gamma ray positron or beta particle?
The alpha particle is much more massive than a beta particle. A beta particle is an electron, which has very little mass. An alpha particle is a helium nucleus, and consists of two protons and two neutrons.
What is the mass number for gamma?
Bz1/3
What is gamma particle symbolized by?
γ (gamma) is a photon.
What decay has no particle associated with it?
All nuclear decay has some kind of particle or particles associated with it. Even the metastable decay of 4399Tcm, a gamma at 142.7 Kev, is considered to be a particle emission, because a gamma is a photon, and a photon is an elementary particle, per our understanding of modern quantum mechanics and particle physics, even though it has no mass at rest state.
