What is the mass of alpha beta and gamma particles is?
Gamma Rays
| Property | α ray | β ray |
|---|---|---|
| Charge | +2e | –e |
| Mass | 6.6466 × 10–27 kg | 9.109 × 10–31 kg |
| Range | ~10 cm in air, can be stopped by 1mm of Aluminium | Upto a few m in air, can be stopped by a thin layer of Aluminium |
| Natural Sources | By natural radioisotopes e.g.92U236 | By radioisotopes e.g.29Co68 |
What is the weight of gamma rays?
Gamma rays are not particles, but a high energy form of electromagnetic radiation (like x-rays, except more powerful). Gamma rays are energy that has no mass or charge.
Is alpha beta or gamma heavier?
Alpha, Beta, Gamma Composition Alpha particles have greater mass than beta particles. By passing alpha particles through a very thin glass window and trapping them in a discharge tube, researchers found that alpha particles are equivalent to helium (He) nuclei.
What is the mass of a beta ray?
4 1/2000
| Type of Radiation | Alpha particle | Beta particle |
|---|---|---|
| Mass (atomic mass units) | 4 | 1/2000 |
| Charge | +2 | -1 |
| Speed | slow | fast |
| Ionising ability | high | medium |
What is the weight of alpha particle?
about 4 amu
Alpha radiation has been identified as helium nuclei that have been stripped of their planetary electrons, and each consists of two protons and two neutrons. α particles thus have a mass of about 4 amu (6.642×10−4 g) each and a positive charge of 2.

What is the mass of Alpha?
Do gamma particles have mass?
Gamma radiation, unlike alpha or beta, does not consist of any particles, instead consisting of a photon of energy being emitted from an unstable nucleus. Having no mass or charge, gamma radiation can travel much farther through air than alpha or beta, losing (on average) half its energy for every 500 feet.
Does beta particle have mass?
Beta particles have a mass which is half of one thousandth of the mass of a proton and carry either a single negative (electron) or positive (positron) charge. As they have a small mass and can be released with high energy, they can reach relativistic speeds (close to the speed of light).

What is mass of alpha particle?

What is the mass of alpha beta and gamma rays?
The total mass of an alpha particle is ~4u or 4 unified atomic mass units, equivalent to ~ 6.64 E-27 kg. A beta particle is just an electron, with a mass ritual to around 1/1822 u, or~ 9.1 E-31 kg. A gamma ray is a photon, and therefore massless (no rest mass).
What is the difference between an alpha particle and beta particle?
An alpha particle is basically a helium nucleus, i.e 2 protons and 2 neutrons. The total mass of an alpha particle is ~4u or 4 unified atomic mass units, equivalent to ~ 6.64 E-27 kg. A beta particle is just an electron, with a mass ritual to around 1/1822 u, or~ 9.1 E-31 kg. A gamma ray is a photon, and therefore massless (no rest mass).
What is the mass of a beta particle in kg?
A β particle is an electron, with mass (9.109 383 56 ± 0.000 000 11) × 10⁻³¹ kg. A γ “particle”/ray is a photon, which so far as currently known is massless.
What are the characteristics of gamma rays?
The Gamma rays carry a large amount of energy and can also travel via thick concrete and thin lead. The below table describes the characteristics of beta, alpha and gamma radiations and compares the masses and charges of the three rays. Negatively charged particles (electrons).
