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.

∙ 13y agoFrancium is most likely a solid at room temperature, but this cannot be known for certain as it is impossible to gather enough francium in one place to test its physical and chemical properties.

∙ 16y agobecause the melting points of alkali metals were plotted and based on the information francium's melting point was extrapollated to less then room temperature.
Wiki User
∙ 14y agoBecause francium is a heavy alkali metal, atomic number 87.

Are unsaturated fats usually solid at room temp whereas saturated fats are usually liquid?
No! the other way around. Unsaturated fats are liquid at room temp whereas saturated fats are solid!
Is potassium found as a solid liquid or gas?
Potassium can be solid, liquid or gas. At normal room temperature and atmospheric pressure it is a solid. Above 63.3oC it is a liquid and above 760oC it is a gas.
Is palladium a solid a liquid or a gas when in room temperature?
At room temperature plutonium is a solid metal.
Is sulfur a gas liquid or solid at room temp?
It takes the form of a brittle, yellow, powdery solid at room temperature.
Is naphthalene a liquid or solid at room temp?
The boiling point of napthalene is 491 K. Therefore this is the temperature where a transition between the gas and liquid phase occurs.
