    B There is a positively charged centre in an atom called the nucleus. Correct Answer Incorrect Answer
    C The negative and positive charges are equal in magnitude. Correct Answer Incorrect Answer
    D The electrons revolve around the nucleus in circular paths Correct Answer Incorrect Answer

    Solution

    RUTHERFORD’S MODEL OF AN ATOM Rutherford was interested in knowing how the electrons are arranged within an atom. Rutherford designed an experiment for this. In this experiment, fast-moving alpha (α)-particles were made to fall on a thin gold foil. There is a positively charged center in an atom called the nucleus. Nearly all the mass of an atom resides in the nucleus. The electrons revolve around the nucleus in circular paths. The size of the nucleus is very small as compared to the size of the atom.
