Structure of the Atom – Notes
Atoms are made of charged particles.
According to Thomson’s Model:
- An atom is a positively charged sphere with electrons set within it.
- An atom is electrically neutral.
Rutherford’s model states that:
- There is a positively charged centre in an atom called the nucleus. Almost all the atom lies in the nucleus.
- The electrons revolve around the nucleus in well-defined orbits.
- The nucleus is much smaller than the atom.
