Lanthanides are all solid at room temperature
The lanthanides and actinides are located in the f-block of the periodic table. The lanthanides are found in the sixth period, spanning from cerium (Ce, atomic number 58) to lutetium (Lu, atomic number 71). The actinides are in the seventh period, ranging from actinium (Ac, atomic number 89) to lawrencium (Lr, atomic number 103). Both series are typically displayed separately at the bottom of the periodic table to maintain its overall structure.

A solid.
The asthenosphere is a flowing solid. It's sort of a liquid and a solid.
Lathanides all lathanides have stable isotopes except promethium, promethium is also the only radioactive lathanide element, hope that helped.

Solid
it is a gas
The general classes of colloids are sols (solid particles dispersed in a liquid), gels (cross-linked networks of solid particles dispersed in a liquid), and emulsions (liquid droplets dispersed in another liquid).
A gas is not a liquid or a solid.
change of a liquid to a solid
Whether the solid will float or sink in a solid-liquid mixture depends on the relative densities of the solid and the liquid. If the density of the solid is greater than that of the liquid, then the solid will sink. If the density of the solid is less than that of the liquid, then the solid will float.
Ice is a solid and when melted it turns into a liquid freeze it again and it is solid
