An atom is made of positively charged pudding like material through whic hnegatively cahrged particels are scattered

I put thompson -

now I am not sure after reading winnepedia maybe rutherford??

Thomson (note the correct spelling) is correct.

To determine which scientist is associated with the description of an atom made of positively charged pudding-like material, with negatively charged particles scattered throughout, you can follow these steps:

1. Start by identifying the key concepts mentioned in the description: positively charged pudding-like material and scattered negatively charged particles.
2. Recall the famous experiments conducted to understand the structure of an atom, specifically the one where positively charged alpha particles were fired at a thin gold foil.
3. Remember that the gold foil experiment was performed by Ernest Rutherford, a New Zealand-born physicist, in 1910.
4. Consider how the results of the gold foil experiment challenged J.J. Thomson's atomic model, which portrayed the atom as a uniform, positively charged sphere with negatively charged electrons embedded within it.
5. Understand that Rutherford's experiment revealed that most of the positively charged alpha particles passed straight through the gold foil, suggesting that the atom is mostly empty space. However, a few alpha particles were deflected at large angles, indicating that the positive charge of the atom must be concentrated in a tiny, dense nucleus at the center.
6. Based on this information, conclude that Ernest Rutherford's work is associated with the description of an atom made of positively charged pudding-like material through which negatively charged particles are scattered.

Therefore, your initial guess was incorrect, and the correct scientist associated with the description is Ernest Rutherford.
