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.
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.
The gamma ray is not a particle but is just an EM wave that transmits energy.
Alpha radiation involves the ejection of a helium nucleus, which has a mass number of 4. This results in the largest change in mass number compared to beta and gamma radiation, which involve the emission of electrons or photons with much smaller masses.
Sort of. A gamma ray is a photon, which is a particle/wave moving at the speed of light, because it is light.Photons are the gauge particles for the electromagnetic force, but they don't carry an electric charge themselves.
The particle that is the same as a helium nucleus is an alpha particle. It consists of two protons and two neutrons bound together. Beta particles are high-energy electrons or positrons, while gamma rays are electromagnetic radiation.
The correct order is c) Alpha particle, beta particle, gamma ray. Alpha particles have the greatest mass, followed by beta particles, and then gamma rays which have no mass.
No, a gamma ray is a massless particle with no rest mass, whereas an electron has a measurable mass.
Gamma rays hasn't a mass number.
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.
A gamma particle is a high-energy photon emitted as a result of radioactive decay. Gamma particles have no mass or charge, allowing them to penetrate deeply into materials and tissues. They are commonly used in various applications such as gamma imaging in medicine and industry.
The alpha, beta, and gamma particles have different masses. An alpha particle has a mass of about 4 atomic mass units (u), which is roughly 6.64 x 10^-27 kg. A beta particle (electron or positron) has a much smaller mass, about 0.0005 u or 9.31 x 10^-31 kg. A gamma particle, which is a high-energy photon, has zero rest mass because it is pure energy.
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.
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.

Gamma rays do not have mass or charge, so they do not contribute to the balance of a nuclear equation that involves the emission of an alpha particle. The alpha particle carries away the mass and charge necessary to balance the nuclear equation.
