I suspect you mean alpha ray as in alpha radiation. In which case an alpha ray consists of helium nuclei. The most common source of such rays is radioactive decay.
The three main types of radiation are alpha radiation, beta radiation, and gamma radiation. Alpha radiation consists of alpha particles, beta radiation consists of beta particles, and gamma radiation consists of gamma rays.
Alpha particles have the least penetrating power compared to gamma rays and beta particles. This is because alpha particles are heavier and more positively charged, which makes them easily absorbed by materials, including skin.
Alpha rays are not typically used for practical purposes due to their low penetration power and high ionizing ability, which makes them potentially harmful to living organisms. In scientific research, alpha rays can be used in applications such as studying nuclear reactions and analyzing materials through techniques like alpha spectroscopy.
The mass of an alpha particle is 4 atomic mass units, 2 protons and 2 neutrons, or about 6.644656 x 10-27 kg.
Alpha particles are helium nuclei -- each particle is composed of two protons and two neutrons. A stream of alpha particles may be called a ray, although as it is not electromagnetic radiation that is probably inaccurate.
a. an alpha particle
alpha particle alpha ray
Alpha and beta are not electromagnetic radiation.
He42 2+
Gamma Ray
alpha ray.
no, it is an alpha particle.
Gamma rays are a part of the electromagnetic spectrum.
ernest Rutherford is the answer....
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.
alpha ray Stream of particles containg two neutrons is, I believe: Alpha Ray
This process is known as alpha decay. During alpha decay, an unstable atomic nucleus emits an alpha particle, which consists of two protons and two neutrons. This emission results in the transformation of the original nucleus into a new, lighter element with a lower atomic number.
