What is an Alpha ray?
An alpha ray is a type of radioactive decay product that consists of two protons and two neutrons, which is essentially a helium nucleus. Alpha rays have low penetration power and can be stopped by a piece of paper or human skin.
What are the names of the three main types of radiation?
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.
What has the least penetrating power gamma ray alpha particle or beta particle?
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.
Mass of alpha particle?
The mass of an alpha particle is 4 atomic mass units, 2 protons and 2 neutrons, or about 6.644656 x 10-27 kg.
Are alpha rays neutrons?
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.

Is the particle with a plus 2 charge a an alpha particle b a gamma ray or c a beta ray?
a. an alpha particle
What is a stream of particles containing 2 neutron and 2 proton?
alpha particle alpha ray
Which is not considered a raditional ray gamma beta alpha or infrared?
Alpha and beta are not electromagnetic radiation.
Formula of alpha ray in physics?
He42 2+
What radioactive emissions are not a particle Neutron Alpha Proton Beta Gamma Ray?
Gamma Ray
The radioactive emission with the weakest penetrating power is the?
alpha ray.
Is heluim-4 nuclei a gamma ray?
no, it is an alpha particle.
Alpha ray gama ray which one is the electro magnetism?
Gamma rays are a part of the electromagnetic spectrum.
Who coined the terms alpha beta gamma ray?
ernest Rutherford is the answer....
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?
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.
What is a stream of particles containing 2 neutrons and 2 protons called?
alpha ray Stream of particles containg two neutrons is, I believe: Alpha Ray
