Activity 4 1. Does the particle or continuous model of the matter better match your observations of liquids and gases?
The particle model
The continuous model

2. Provide two examples of observations from the activities in this investigation to use as evidence to support your argument. Explain why those observations support your choice for a particle or continuous model of matter.

3. Return to your earlier ideas about what would happen if you cut a piece of paper in half over and over again. Do you still agree with your original claim (that you could or could not cut the paper in half forever)? What changes would you make to your original ideas and what evidence and reasoning caused you to change your thinking?

According to rutherford's nuclear theory, most of the volume of an atom is , so the volume of a hydrogen atom cannot be mostly due to the proton. according to rutherford's nuclear theory, the core of an atom (nucleus) contains most of of an atom and is , so the majority of the mass of a fluorine atom cannot be due to its nine electrons. according to rutherford's nuclear theory, the number of negatively charged particles outside the nucleus the number of positively charged particles within the nucleus, so a nitrogen atom has 7 protons and 7 electrons, while a phosphorous atom cannot have 15 protons and 150 electrons. word bank: dense, empty space, more than, mass, particles, the same as, less than, positively charged, negatively charged
