Show hintHide hint
Think of the basic building parts of an atom.
Question 2.
What charge does a proton carry?
Show hintHide hint
Consider its counterpart particle.
3Question 3.
What did Rutherford conclude about the structure of the atom based on his experiments?
- It consists only of electrons.
- It is mostly empty space with a dense nucleus.
- It has a fixed number of protons and no electrons.
Show hintHide hint
Think about the implications of the alpha particle scattering experiment.
4Question 4.

- True
- False
Show hintHide hint
Remember the basic properties of subatomic particles.
Question 5.
Given that Rutherford established the concept of the nucleus, propose an experimental setup to investigate the size of the nucleus versus the size of the entire atom.
Show hintHide hint
Think about how Rutherford conducted his own experiments.
Question 6.
If the mass of a proton is approximately 1 unit and that of a neutron is also 1 unit, how would you find the total mass of an atom with 6 protons and 6 neutrons?
