In Thomson’s model, electrons were illustrated as small particles distributed within the positively charged sphere, similar to seeds in a watermelon.
Thomson compared the spread of positive charge within an atom to the edible red part of a watermelon, suggesting it was spread throughout the atom.
Thomson likened the structure of an atom to a Christmas pudding, where electrons were compared to currants embedded within a positively charged sphere.
Understanding the arrangement of electrons and protons within an atom was necessary to develop a more accurate model of atomic structure and explain various chemical phenomena.
