Web11 sep. 2024 · What is the trend in melting points in group 7? Trends. The boiling and melting points increase as you go down the group. This is because the strength of the Van Der Waals forces (or induced dipole-dipole interactions) increases since the atoms have more electrons as you descend the group. WebQuestion: Why does the melting point increase going down group 7&0. Why does the melting point increase going down group 7&0. Expert Answer. Who are the experts? …
