Question

which scientist developed the first model of the atom that proposed the structure of the inside of an atom?
dalton
bohr
rutherford
thomson

Explanation:

Dalton's model viewed atoms as indivisible solid spheres with no internal structure. Bohr's model focused on electron energy levels, building on earlier work. Rutherford's model identified a central nucleus, but it was not the first to propose internal structure. J.J. Thomson's "plum pudding" model was the first to suggest atoms have internal structure, with embedded electrons in a positive charge cloud.

Answer:

Thomson
