Alpha particles are made up of 2 protons and 2 neutrons, this gives them a strong positive charge.
They are slow moving and can be stopped by a sheet of paper or skin.
Their charge makes them highly ionising which means that they can damage living tissue if they get inside the body.
Beta Particles are made up from electrons it's charge is zero. Their mass is very light (1/1836) .
Beta's penetration abilities can travel through Aluminium or a thin sheet of a metal
Gamma Particles are made up from a electromagnetic wave it's charge is negative it doesn't have a mass it can travel through Lead

Is Light has many of the properties of waves but light can also act as though it is a stream of?
... particles.... particles.... particles.... particles.
What is A thin sheet of aluminum can block?
In terms of nuclear radiation, a thin sheet of aluminium is capable of blocking both alpha particles (helium nucleus: 2 protons + 2 neutrons) and beta particles (electrons or positrons).
Alpha and beta particles and gamma rays are examples of?
Different types of radiation
How did the result of gold foil experiment lead Rutherford to recognize the existence of atomic nuclei?
By beaming alpha particles through gold foil and witnessing some of them deflecting, there had to be a mass larger than an alpha particle in the atomic structure. This disproved the plum pudding theory of the atom, as electrons would not have had enough mass to deflect the larger alpha particles.
Which type of radiation is easiest to shield?
The type of radiation that is easiest to shield are alpha particles. They are also the least harmful. Alpha particles consist of two protons and two neutrons bound together into a particle identical to a helium nucleus.
What effect does humidity have on alpha particles?
Alpha particles can be absorbed by water.
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.
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.''
Why a spherical sulphide screen is used in alpha ray scattering experiment?
Because it was cheap and had good fluorescence properties, meaning high light output and therefore better energy resolution.
How do the properties of radium differ from the properties of the compounds formed by radium?
Radium glows in the dark and is radioactive. When it decays into Radon gas, it emits alpha particles. It is fairly close to its compound radiumchlorite because like radium, it also decays emiting alpha particles. However, radiumchlorite is used to help cure canser. Overal, radium is like its most comon compound but can also have properties not related to its compounds at all.
What is the range of beta particles in air as compare to alpha particles?

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.
