Atomic models have changed over the decades. Two early atomic models can be seen here. There is a dramatic change in the models, as Rutherford experimented with the cathode ray tube and charged particles. Differentiate between the two models by selecting the main difference between the models.
Question 5 options:
Rutherford's model shows negative charges dispersed throughout the atom
Rutherford's model shows negative particles orbiting the central nucleus
Rutherford's model shows the positive charge of an atom as a very small area
Thomson's model shows at sea of negative charged particles surrounding a small, positive area

You are a researcher for a golf club manufacturer. you are given two identical looking cubes of a metal alloy. you are informed that they are made of the exact same material, but one is crystalline, whereas the other is amorphous. it is your job to determine which one is amorphous this one is more stress-resistant and is useful in reinforcing golf clubs. which of the following is the best way to determine which is which? a. determine the density of each cube. the more dense one is the amorphous solid. b. melt both cubes and look for a broader range of melting temperatures. the one that melts over a broader range of temperatures is the amorphous solid. c. determine the density of each cube. the less dense cube is the amorphous solid. d. melt both cubes and measure the range of melting temperatures. the one that melts over a narrower range of temperatures is the amorphous solid.
