Explanation:

Question 1

J.J. Thomson discovered electrons (negative subatomic particles) through cathode ray experiments. So the correct answer is Thomson (RED).

Rutherford's gold foil experiment showed that atoms have a dense, positively - charged nucleus. So the correct answer is nucleus (PINK).

Democritus was the first to propose that matter is composed of indivisible small particles (atomos). So the correct answer is Democritus (LIGHT BLUE).

Answer:

Thomson (RED)
