Who said that 'atoms are negatively charged particles'?
It's J.J. Thomson He had the plum pudding experiment The answer is Thomson
Why do you think Thomson hypothesized that electrons must come from inside an atom?
Thomson had two pieces of evidence: 1- No matter what metal he used for the disk, the particles produced were indentical. 2- The particles had about 1/2000 the mass of a hydrogen, the lightest atom. These experiments provided the first evidence that atoms are made of even smaller particles.
How did Thomson experiment change Dalton atomic model?
John Dalton stated "all atoms of a given element are identical"; discovery of isotopes by Thomson infirmed this old hypothesis.
What evidence did Thomson that his glowing beam contained negative particles?
The cathodic rays beam was deflected by the atomic nucleus.
How is Thomson's model based on the experiment of passing alpha particles through the gold foil?
The results of this experiment led to the model of the atom called "Rutherford's model", rather than Thomson's model, which it basically disproved. Some of the alpha particles were deflected in ways that suggested to Rutherford that most of the atom's mass was concentrated in a positively charged "nucleus".

Why was it important for Thomson to repeat his experiment?
Thomson did the experiment various times to observe if the particles behave the same way. How they did he determined they were the same kind later called electrons.
How did the Thomson's experiment change Dalton's atomic model?
Thomson discovered that the atom contained smaller particles called electrons
