What are α-particles?
Asked by Topperlearning User | 30th Mar, 2016, 05:17: PM
α-particles are doubly-charged helium ions. Since they have a mass of 4 u, the fast-moving α-particles have a considerable amount of energy.

- what is the meaning of equipment
- what is meant by nucleon??
- How are scientist observe the atoms in an element?
- What are the observation of α-particle scattering experiment?
- Why did Rutherford select a thin sheet of gold foil for his experiment?
- Where does the most of the mass of an atom reside? Which particles contribute to most of the mass of an atom?
- One of the observations during α-particle scattering is that most of the fast moving α-particles passed straight through the gold foil non-deviated. What does this observation explain?
- During Rutherford's experiment, a very small fraction of alpha-particles were deflected by 180o, what does this prove?
- In Rutherford's experiment, alpha-particles got deflected through various angles in different proportions. How is this observation made?
