THOMSON'S ATOMIC MODEL:-
According to Thomson's atomic model positive charge is distributed uniformly over the entire body of the atom while the electrons are embedded in it. Similar to the seeds in a water melon.
Thomson's model failed to explain observed spectra emitted by an atom .
A sodium cation has different number of electrons from: (1) O 2- (2) F - (3) Li + (4) Al +3 Ans: Li +
