Question

1. fill in the blanks regarding the conclusion drawn by rutherford. the atom is made of mostly ____________. in the center, there is a small, dense, __________ charge nucleus that makes up most of the atoms ____________. 8. how did thomsons cathode ray tube experiment show the electron is negatively charged? what other conclusions about the structure of the atom did he draw?

Explanation:

For question 7, Rutherford's gold - foil experiment led to the understanding that atoms are mostly empty space, with a small, dense, positively - charged nucleus that contains most of the atom's mass. For question 8, in Thomson's Cathode Ray tube experiment, the cathode rays were deflected by electric and magnetic fields in a way that indicated they were negatively charged. He also concluded that atoms contain smaller, negatively - charged particles (electrons) and proposed the "plum - pudding" model of the atom where electrons were embedded in a positively - charged sphere.

Answer:

1. empty space; positively; mass
2. The cathode rays were deflected by electric and magnetic fields in a way consistent with negative charge. He concluded that atoms contain smaller, negatively - charged particles (electrons) and proposed the "plum - pudding" model of the atom where electrons were embedded in a positively - charged sphere.
