WebApr 4, 2013 · Why does the melting point get lower going down the Alkali Metal Group with increase in atomic number? Ok, you're looking for a generalization of what happens to the melting point as you go down a column in the periodic table. Think of the metal atoms as cations $\ce{M^+}$ and anions $\ce{M^-}$ packed into a crystal like NaCl. ... WebApr 6, 2024 · So these three must interact with LDF. We can see that the molecular mass of sulfur < selenium < tellurium ( S < S e < T e ). From what we know, the bigger the mass, the larger the boiling point. From this point we can tell that the trend of the boiling points is. H X 2 S < H X 2 S e < H X 2 T e < H X 2 O.
