How were Alpha decay and beta decay discovered?
Alpha decay was discovered in 1899 by Ernest Rutherford, who observed that certain radioactive elements emitted alpha particles. Beta decay was discovered in 1896 by Henri Becquerel and later studied by Ernest Rutherford and others, who noticed that certain radioactive elements emitted beta particles. These discoveries were important in understanding the nature of radioactivity and led to further research in nuclear physics.
Where could one locate Alpha particles?
Alpha particles are most commonly found when alpha decay occurs. An alpha particle is emitted during alpha decay. Further information about alpha particles can be found on the Wikipedia website.
The existence of alpha decay in radioactive uranium was first discovered by?
The existence of radiation was discovered in 1896 by Henri Becquerel in the course of experiments involving uranium salts, though the nature of it was unknown. The nature of the alpha particle was discovered by Ernest Rutherford, and he showed it was essentially an helium nucleus in 1907.
What correctly describes the charge of beta particles and alpha particles?
Beta particles have a negative charge, while alpha particles have a positive charge. Beta particles are electrons or positrons, while alpha particles are helium nuclei consisting of two protons and two neutrons.
Who was the scientist who showed that alpha particles are helium nuclei?
Ernest Rutherford discovered that alpha particles are helium nuclei during his famous gold foil experiment in 1909. This experiment provided evidence for the existence of a dense, positively charged atomic nucleus.
What are the 3 types of radioactivity discovered by Rutherford?
The three types of radioactivity discovered by Rutherford are alpha particles, beta particles, and gamma rays. Alpha particles are positively charged, beta particles are electrons or positrons, and gamma rays are high-energy electromagnetic radiation.
Who discover alpha particles?
Ernest Rutherford and Paul Villard discovered alpha particles in the period 1899 to 1900, by classifying radiation into three types, alpha, beta, and gamma. Ernest Rutherford and Thomas Royds subsequently proved, in 1907, that alpha particles were helium ions.
Define the three types of Radiation alpha particles beta particles gamma particles and list the name of the scientist who discovered it?
Ernest Rutherford discovered radiation. Alpha is most harmful is ingested, it cannot penetrate the sign, nor paper or metal or lead, beta is able to penetrate paper and metal, and gamma, the most harmful of the three is able to penetrate paper, metal, lead, and skin. beta can penetrate the skin after a long period of time.
The kind of particle Rutherford used to shoot through gold foil?
Rutherford shot high-energy alpha particles (two protons and two neutrons, or a helium nucleus) at the gold foil. A small fraction of these alpha particles bounced back, and that is how Rutherford discovered the nucleus.
What effect does humidity have on alpha particles?
Alpha particles can be absorbed by water.
What did Rutherford call the region that deflected the alpha particles?
Rutherford called the region in the gold foil experiment that deflected alpha particles the "nucleus." He discovered that the positive charge and most of the mass of an atom were concentrated in this small, dense region.
Who discovered beta rays?
Ernst Rutherford discovered beta decay. Henri Becquerel discovered that there were emissions somewhat like X-rays originating from uranium. Ernst Rutherford discovered that two different kinds of emissions were coming from the uranium, and he named these alpha and beta. He published a paper on this in 1897.
How were Alpha decay and beta decay discovered?

What was rutherfords experiment?
he shot tiny alpha particles throug a piece of gold foil. -Apex
How many radioactive elements are discovered uptill now?
There are currently 38 radioactive elements that have been discovered. These elements have unstable nuclei that undergo radioactive decay, emitting radiation in the form of alpha particles, beta particles, or gamma rays.
