Question

1. what did jj thomson’s plum pudding model disprove about dalton’s atomic theory?

Dalton's atomic theory stated atoms are indivisible. JJ Thomson's plum pudding model (discovering electrons) showed atoms have sub - atomic particles, disproving the "indivisible atom" part of Dalton's theory.

JJ Thomson's Plum Pudding Model (by discovering electrons) disproved Dalton's idea that atoms are indivisible (i.e., atoms have sub - atomic particles, so they are not the smallest, indivisible units of matter).
