The melting point of francium is not measured, only supposed by comparison with the melting points of the other alkali metals.

Melting and boiling points of francium?
Now we don't have sure data. Melting point: possible 30 0C Boiling point: possible 677 0C
What is francium's melting an boiling points?
Not exactly known. The probably melting point of Fr: 27 0C The probably boiling point of Fr: 677 0C
What are some fun facts about Alkali metals?
The Alkali Metals are: -lithium -sodium -potassium -rubidium -cesium -francium These metals are silvery solids with low densities and melting points.
How does the arrangement of ions in a solid help to explain the high melting points of most ionic compounds?

Which material has higer melting point NaCl or sugar explain?
Generally inorganic ionic salts have higher melting points than organic materials; the bonds are stronger.
Do nonmetals have higher melting points or lower boiling points?
lower melting points
Is francium a gas liquid or a solid at room temp?
It is considered to be a solid at room temperature 20oC.Although, francium has a very short half-life (22 miuntes!), so the heat and energy given off by its decay may mean it is technically a liquid at room temperature (its melting point is about 27°C, even lower than caesium). However, this would depend greatly on how much francium you actually have. And, because of the intense radioactivity, it would probably be impossible to gather a significant amount of solid Fr.Francium is a solid at standard temperature and pressure.
Which ions have high melting points?
positive ions have high melting points
Do proteins have definite melting points?
Different proteins have different melting points.
Which alkali metal is most likely to melt on a hot day?
Cesium, rubidium, and francium could all melt on a hot day. (Cesium and francium in the 80s Fahrenheit and above, and rubidium just over 100oF).
