Alpha particles contains helium ions or atoms or nucleus?if it contains helium nuclei then how this alpha particles discovered before the discovery of nucleus by rutherford?

In 1899, Rutherford had discovered alpha and beta rays from uranium. Today we know that they are not rays, they are particles; alpha is a nucleus of helium and beta is an electron.

- 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?
- What are α-particles?
- 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?
