ia berpendapat bahwa di dalam atom seharusnya juga terdapat partikel bermuatan positif untuk menetralkan atom tersebut. Melalui penemuannya, Thomson berhasil memperbaiki teori atom Dalton. Dapat disimpulkan, teori atom Thomson isinya adalah atom dianggap sebuah bola yang muatan positif dan negatifnya tersebar merata di permukaannya. Teori ini juga terkenal sebagai model roti kismis atau “plum pudding model”. Kelebihan: menemukan partikel yang lebih kecil dari atom yaitu elektron

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.

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.
