Alpha particles are the strongest of the three known types of radiation (alpha, beta, & gamma). Although the strongest, the alpha particles are the least penetrating.They do not tend to penetrate any substance.A well-known example is your skin. Alpha particles do not penetrate your skin barrier. However, alpha particles energy is high and is a cause of skin cancer and genetic mutations.
If a mixture is electrically neutral, for every alpha particle (which has a charge of +2), there must be two beta particles (each with a charge of -1) to balance the charges. So there are two more beta particles than alpha particles in the balloon.
Gamma rays have higher penetrating ability compared to alpha and beta particles. Gamma rays can penetrate through most materials, while alpha particles can be stopped by a sheet of paper and beta particles by a few millimeters of aluminum.
Paper can stop alpha particles because paper has a higher density compared to air, which makes it more likely that the alpha particles will collide with the atoms in the paper, losing energy and stopping their movement. Additionally, the small size of alpha particles means they are easily absorbed by the materials they come into contact with.
No, alpha particles are not the most radioactive emission. Gamma rays are more penetrating and more energetic than alpha particles, making them the most dangerous and damaging form of radiation.
Alpha radiation is emitted from the amercium button in a smoke detector. When smoke goes into the smoke detector it blocks the stream of alpha particles emitted from the americium. That triggers an alarm.
Alpha particles can be absorbed by water.
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.
Alpha decay is the type of radioactive decay in which positive particles, specifically alpha particles, are emitted. These alpha particles consist of two protons and two neutrons bound together, giving them a positive charge.
some of alpha particles were deflected through an angle of 90 degree
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.
The symbol of the alpha particle is the small Greek letter alpha, α

No. You can produce alpha particles in a number of ways, but that's not really "cloning" as the term is usually used, even if all alpha particles are indistinguishable from each other.
Alpha particles can be blocked by a block of lead due to their relatively low penetrating power, while beta particles may require a thicker shield, such as a piece of aluminum or plastic, depending on their energy. Lead is not as effective at blocking beta particles as it is for alpha particles.
