Estimated values:
- Melting point: 22-25 0C
- Boiling point: 660-665 0C
The melting point of Calcium is 839℃ and the boiling point is 1484℃.
Melting point −209.86°C; boiling point −195.8°C
A boiling point is a point on the temperature scale at which a substance begins to boil. A melting point is a point on the temperature scale at which a substance freezes. Melting and boiling points are unique to different types of elements.
The boiling point of francium is approximately 677 degrees Celsius (1250 degrees Fahrenheit). Francium is extremely rare and radioactive, so its properties, including its boiling point, are difficult to measure accurately.
The boiling point is always higher than the melting point.
Now we don't have sure data. Melting point: possible 30 0C Boiling point: possible 677 0C
Not exactly known. The probably melting point of Fr: 27 0C The probably boiling point of Fr: 677 0C
Francium has a very low boiling point of approximately 677°C (1251°F). It is the second rarest naturally occurring element, and its melting and boiling points are among the lowest of all the elements.
The boiling point of francium is very probable approx. 677 0C.
The metal francium has a much lower melting point than platinum has.
It doesn't much matter; there's only a few grams of francium on the planet, and it's unstable anyway. You'll never see any. But in case you really want to know, its melting point is predicted to be very near room temperature - about 27 Celsius. It has no stable isotopes; the longest half life of any of them is 22 minutes.
The melting point of Calcium is 839℃ and the boiling point is 1484℃.
The melting point of francium is not measured, only supposed by comparison with the melting points of the other alkali metals.
