This is the Plum Pudding Model. It was developed by JJ Thompson. He proposed this because of the Cathode ray experiments that he completed in the 1890s. These experiments proved the existence of negatively-charged particles associated with electrons. The Plum Pudding Model suggests negatively charged particles embedded in a ball of positive charges.

1911: Ernest Rutherford's gold-foil experiments demonstrate that atoms have a solid nucleus. Top: Expected results: alpha particles passing through the plum pudding model of the atom undisturbed.  Bottom: Observed results: a small portion of the particles were deflected, indicating a small, concentrated charge.

How did Rutherford figure out the structure of the atom without being able to see it? Simulate the famous experiment in which he disproved the Plum Pudding model of the atom by observing alpha particles bouncing off atoms and determining that they must have a small core.

Model atom Thomson dikenal sebagai "plum pudding model" atau yang sering kita dengar "model roti kismis". Thomson menyatakan bahwa, atom terdiri dari awan bermuatan positif yang terdistribusi sedemikian rupa dengan muatan negative tersebar secara random di dalamnya.

JJ Thomson's Plum Pudding Model: negatively charged particles are surrounded by a positively-charged ball. Founded from the cathode ray experiments.
