Which group of elements is characterized as having little to no reactivity?  

C. Alkali Metals

 Noble gases

Explanation:  Noble gases constitutes the extreme right position in the periodic table,

They are have the smallest atomic radius and are the most unreactive elements present in the whole periodic table. There outermost shell of electrons that is valence shell of electrons is completely full thus there is no chance of loss or gain of electrons.

Thus noble gas elements are also known as Inert Gases.

we can conclude that the melting point of table salt is above room temperature (it's actually 801 deg c). the melting point of mercury must be below room temperature (- 39 deg c).
