Answers:
Alpha radiation is a helium nucleus.
Electrons are beta radiation
Alpha radiation is easily stopped by paper or clothing.
The order of radioactive particles from most to least penetrating ability is gamma, beta, alpha.
Beta radiation can be stopped by thick wood or a sheet of aluminum.
Step-by-step explanation:
1. only unstable nuclei give off radiation. In an unstable atom, the nucleus changes by giving off a neutron to get back to a balanced state. As the unstable nucleus changes, it gives off radiation and is said to be radioactive.
2. Gamma Rays can easily penetrate barriers that can stop alpha and beta particles, such as skin and clothing. several inches of a dense material like lead, or even a few feet of concrete may be required to stop them.
3. Alpha radiation is a helium nucleus.
4. A beta particle, also called beta ray or beta radiation (symbol β), is a high-energy, high-speed electron or positron
5. Gamma rays are a high-energy form of electromagnetic radiation.
6. Alpha radiation is easily stopped by paper or clothing.
7. Alpha denotes the largest particle, and it penetrates the least. Alpha particles carry a positive charge, beta particles carry a negative charge, and gamma rays are neutral.
8. Gamma radiation is a rigid electromagnetic radiation at the short-wave edge of the electromagnetic wave spectrum.
9. Beta particles can travel a few metres through the air and can be stopped by a thin sheet of aluminum or a piece of wood a few centimetres thick.
