-219°c medium density
-218°c highest density

Explanation:

• Solid: In a solid state, particles are closely packed (close spacing). They have the least amount of energy among the three states, so they only vibrate in place. For Neon, the temperature at which it is solid is \(-259^{\circ}C\).
• Liquid: In a liquid state, particles have more energy than in a solid. They are in medium spacing. The particles vibrate and slide around but are still connected. For Neon, the temperature at which it is liquid is \(-246^{\circ}C\).
• Gas: In a gas state, particles have the most energy. They are far apart (spacing far apart) and move freely.

Answer:

• Solid: Close spacing, Particles vibrate in place, \(-259^{\circ}C\)
• Liquid: Medium spacing, Particles vibrate and slide around but are still connected, \(-246^{\circ}C\)
• Gas: Spacing far apart, Particles move freely
