Isotopes with fewer neutrons have less mass, leading to weaker intermolecular forces, resulting in lower densities and lower melting and boiling points compared to isotopes with more neutrons. The presence of more neutrons increases the mass and the strength of intermolecular interactions, thus increasing the density and melting and boiling points.
Melting point: the temperature at which a solid become a liquid. Boiling point: the temperature at which a liquid become a gas.
Melting and boiling points are important characteristics of materials: they are needed in industry and in laboratory.

Because they are not pure compounds !

Einsteinium is a synthetic element with no stable isotopes and its physical properties are not fully known. The melting and boiling points of einsteinium have not been precisely determined due to its limited availability and instability.
Melting and boiling points are different for each compound or element.
Elements have fixed melting and boiling points, while compounds have varying melting and boiling points depending on their composition. Mixtures do not have fixed melting and boiling points, as they are composed of multiple substances which each have their own individual melting and boiling points.
No, different liquids have different boiling and melting points depending on their chemical composition. The boiling point is the temperature at which a liquid turns into a gas, while the melting point is the temperature at which a solid turns into a liquid. Each liquid has its own unique set of physical properties that determine its specific boiling and melting points.
