What is alpha radiation How is it symbolized?
Alpha Decay The bottom number in a nuclear symbol is the number of protons. That means that the alpha particle has two protons in it that were lost by the uranium atom. The two protons also have a charge of +2. The top number, 4, is the mass number or the total of the protons and neutrons in the particle.
Which symbol represents an alpha particle?
For example, an alpha particle (helium nucleus) is represented by the symbol 42He, where He is the chemical symbol for helium, the subscript 2 is the number of protons, and the superscript 4 is the mass number (2 protons + 2 neutrons).
What does the 4 in 42he mean?
STUDY. A nuclide is. An atom with a specific number of neutrons and protons. What does the 4 in 4-2 He mean? The mass number.
What can alpha radiation be stopped by?
In general, alpha particles have a very limited ability to penetrate other materials. In other words, these particles of ionizing radiation can be blocked by a sheet of paper, skin, or even a few inches of air.
What are the symbols for alpha beta and gamma rays?
Alpha, beta and gamma
| Type of radiation | Greek symbol | Charge |
|---|---|---|
| Alpha | α | Positive 2+ |
| Beta | β | Negative 1- |
| Gamma | γ | No charge |
