Answer 1

Rutherford’s alpha-particle scattering experiment established that protons are not evenly distributed throughout an atom.

Result of Rutherford's model of an atom:

• The whole mass and positive charge of an atom are concentrated in a very small region at the centre known as the nucleus.
• The positive charge on the nucleus is due to protons. Since the number of protons is different for atoms of different elements, therefore, the magnitude of positive charge on the nucleus is different for atoms of different elements.
• The nucleus is surrounded by negatively charged particles called electrons.
• The number of electrons in an atom is equal to the number of protons (positively charged) in the nucleus. Thus, the atom as a whole is neutral.
• The electrons are revolving around the nucleus at a very high speed.
• Most of the space in an atom is empty.
