Free Response 1  The element neon (Ne) is a colorless gas that exhibits an orange-red glow when placed in an electric field, making it useful in signs. Ne has a melting point of -249 oC and boiling point of -246 o Part A. Please show Ne and its interactions at -247 oC and -200 oC.  Please label all interactions (ie. London dispersion forces and/or covalent bonds) at each temperature and label the states of matter. Be sure to include a key. Part B. Please explain, using your understanding of forces and energy, what is happening on the molecular level as Ne is heated from –247 oC to -200 oC as shown in Part A.  (Use 1-2 sentences)
