The results of Rutherford’s gold foil experiment demonstrated that the nucleus occupies a very small amount of the total space inside an atom.

Further Explanation:  

• In Rutherford's gold foil experiment, the beam of alpha particles hit the thin gold foil. Some of them follow the same path after hitting the gold foil while some of them deflect from the path and bounces back indicating the presence of solid mass at the center of atom.  

• From this experiment, he concluded that most of the part in atom is empty because most α-particles go through the gold foil without being deflect. In addition, very few particles deflected from the path, indicating that very less space occupied by positive charge.

6.

If element Q has 11 protons, its atomic number is 11.

Further Explanation:  

• Atomic number of an element is number of protons present in nucleus of an atom. Atomic and charge number is same of the nucleus and identifies an element uniquely.

• In an atom, electron and proton are equal in number.

7.

The region in which an electron is most likely to found called an energy shell or energy level.

Further Explanation:  

• An atom consists of a small nucleus and energy shells or energy levels.

• Nucleus consist protons and nucleons while the energy level consist electrons.

• Charge on proton is positive while charge on electron is negative.

• In an atom, proton and electron are equal in number.

8.

An atom in which an electron has moved to a higher energy level is in excited state.

Further Explanation:  

• Excited state of the atom is a state, which occurs due to moving of electrons from a lower energy shell to higher energy shell.  

• When a valence electron absorbs energy from photons, it gets excited to a higher energy shell from a lower energy shell and occurs only when electron is already excited to its lower energy shell from a ground state.
