Thomson's 'plum pudding' model of the atom pictured the atom as:
AEmpty space with no charges
BA sphere of positive charge with negatively charged electrons embedded in it like plums in a pudding
CA nucleus surrounded by orbiting electrons
DAn atom of pure neutral matter
Answer & Solution
Correct answer: B. A sphere of positive charge with negatively charged electrons embedded in it like plums in a pudding
In 1898 Thomson proposed that atoms are spheres of positive charge with electrons stuck inside, making the whole atom electrically neutral (negative electrons + positive sphere). This model was eventually replaced by Rutherford's nuclear model after the gold-foil experiment.
