Any element that needs to emit it in order to stabilise. And they are not the nuclei of the element, they are made up of two protons and two neutrons, and it is also the most ionising radiation as well.

∙ 13y agoAlpha particles are actually the least penetrating form of nuclear radiation, with gamma radiation as the most penetrating and beta radiation in the middle. This is because the alpha particle is the largest, consisting of 2 protons and 2 neutrons, and the beta particle is the second largest as it is just an electron. Gamma radiation is simply an electromagnetic wave and as such it has no particles and is much more penetrating than the other types of radiation.

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.
Do the alpha particles in Rutherford's experiment contain electrons?
Alpha particles are helium-4 nuclei; they do not contain electrons.
How does Alpha particles affects us?
They don't, or at least, the effect is negligible. Alpha particles can be deflected with a sheet of paper.
What type of nuclear radiation can be blocked by a block of lead Beta particles or alpha particles?
Both Beta and alpha particles can be blocked by a block of lead. Alpha particles can even be blocked by a sheet of paper, and beta particles can be blocked by a thin aluminium plate.
What correctly describes the charge of beta particles and alpha particles?
Beta particles, from beta- decay, have a charge of -1. Beta particles, from beta+ decay, have a charge of +1. Alpha particles have a charge of +2.
What effect does humidity have on alpha particles?
Alpha particles can be absorbed by water.

What gives off alpha particles?
Alpha particles are a type of particle of radiation that is emmited by certain radioactive materials. The materials that give off Alpha particles are called ''Alpha emitters.''

Name the nuclear radiation that can be easily stopped by skin or cloths?
alpha particles.
If the mixture of electrically neutral how many more beta particles than alpha particles are in the balloon?
alpha particles would have twice as many beta particles
Why were few alpha particles deflected?
some of alpha particles were deflected through an angle of 90 degree
What particles can thorium emit?
Alpha particles but also electrons and gamma radiations (Th 232).
Alpha particles and beta particles differ in?
Alpha particles are positively charged helium nuclei while beta particle are negatively charged electrons . Alpha particle have 4u mass while beta particles have zero mass.
What is Alpha radiation stopped by?
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.
What is the alpha particles?
The symbol of the alpha particle is the small Greek letter alpha, α
How does Alpha particles affects us?
They don't, or at least, the effect is negligible. Alpha particles can be deflected with a sheet of paper.
