According to the video, what are the three elementary particles that make up an atom?

Neutrons, protons, and electrons

Describe the relative amount of empty space inside an atom, as explained in the video.

The video states that 99.999999999999% of an atom's volume is empty space.

Explain how the video uses the analogy of rice and sand in a room to describe the size of atoms.

The video uses the analogy of a fingertip being the size of a room, then filling that room with rice (cells), zooming in until one cell is the size of the room, filling it with rice (proteins), and then filling the spaces with sand (atoms) to illustrate how small atoms are relative to cells and proteins.
