WebThe melting and boiling points of the Group 7 elements increase going down the group which indicates that the elements become less volatile. Going down the group, the boiling point of the elements increases which means that the volatility of the halogens decreases. This means that fluorine is the most volatile and iodine the least volatile.
WebThe size of a molecule influences its melting point as well as its boiling point, again due to increased van der Waals interactions between molecules. What is different about melting … Web- Most have high melting and boiling points. - The melting point depends on the strength of the metallic bonds holding together the atoms in the giant metallic lattice. For most metals high temps are needed to provide the large amount of energy to overcome the strong electrostatic attraction between the cations and electrons.
