According to Dalton, atoms are indivisible and unbreakable which suggest the atom to be like According to Thomson, atom is like plum pudding i.e. negative charged particles are floating within a soup of scattered positive charge. According to Rutherford, an atom's positive charge i.e. protons and the majority of its mass due to heavy protons are packed into a very small volume which is called nucleus. and electrons are revolving around the nucleus in orbits. this model is also known as planetary model. Bohr's Model was based on quantum theory, according to which the electrons revolve around the nucleus in circular orbits of fixed energy. |
