Why does melting point of group 6 oxides decreases down the group?
VedaantArya:
Group 6? Chromium's or Oxygen's? Please clarify, since Chromium's group's elements' oxides' melting points' order seems out of bounds for Secondary School, and Oxygen family's seems absurd to be asked.

The electronegativity decreases as we move down the group. Therefore, it decreases as we move from oxygen to polonium due to increase in nuclear size. ... The Melting and Boiling Points: As the atomic size increases from oxygen to tellurium, the melting and boiling points also increase.
