Why is the density of francium unknown?

It can be found in uranium deposits or created in the laboratory by bombarding the element thorium with protons. But at any given time there are no more than 20 to 30 grams of francium in the earth’s crust! This would make it difficult to find enough francium to weigh.

What element has a density of 3.26 g ml?

Diamond
Diamond has a density of 3.26 g/cm3.

Is francium a solid liquid or gas?

Francium is a chemical element with symbol Fr and atomic number 87. Classified as an alkali metal, Francium is a solid at room temperature.

What is Sr in the periodic table?

strontium
strontium (Sr), chemical element, one of the alkaline-earth metals of Group 2 (IIa) of the periodic table.

What is carbons hardness?

0.4. Notes on the Mohs Hardness of particular elements: Carbon: Value given for graphite. Diamond value is 10.0. Praseodymium: converted from Vickers scale.

Which element has the greatest density at STP?

The first chemical element with the lowest density is Hydrogen and the highest density is Osmium.

Is francium Reactive or nonreactive?

The most reactive metal on the periodic table is francium.

What is 38 on the periodic table?

Strontium
The Scottish village was called Strontian, the mineral found there, strontianite and the new element strontium. So, it seems there never was an eminent professor, Stront, commemorated by element number 38….

Discovery date	1790
Origin of the name	Strontium is named after Strontian, a small town in Scotland.
Allotropes

What is the density of francium in cm3?

Density of Francium is –g/cm3. Typical densities of various substances are at atmospheric pressure. Density is defined as the mass per unit volume. It is an intensive property, which is mathematically defined as mass divided by volume:

How big is the melting point of francium?

Atomic weight of Francium is 223 u or g/mol. Melting point of Francium is 27 °C and its the boiling point is 677 °C. Francium is an extremely unstable and highly radioactive metal discovered in the middle of the last century by a group of French scientists and named after their homecountry.

What are the properties of francium in CSFR?

Francium is an alkali metal whose chemical properties mostly resemble those of caesium. Francium has slightly higher ionization energy than caesium, also it should have higher electron affinity than caesium. The CsFr molecule is predicted to have francium at the negative end of the dipole, unlike all known heteroatomic alkali metal molecules.

What is the chemical symbol for francium, Fr?

Atomic Number of Francium is 87. Chemical symbol for Francium is Fr. Number of protons in Francium is 87.
