The most stable oxidation state of francium is +1. Francium readily loses its single valence electron to attain a stable electron configuration similar to the noble gas configuration of cesium.

Why sodium francium is the most reactive metal?

Sodium and francium are both highly reactive metals due to their low ionization energy and strong desire to lose an electron to achieve a stable electron configuration. Francium is more reactive than sodium because it has a larger atomic radius and lower ionization energy, making it easier for francium to lose its outermost electron. This increased reactivity makes francium the most reactive metal among all the elements.


How many electrons are in francium?

The atomic number of francium is 87. This means that it has 87 each of protons and electrons. The number of neutrons depends on the isotope, but the most common one, Fr-223, has 223 - 87 = 136 neutrons. (The number of neutrons is always the isotope mass number minus the atomic number.)


What is the most electropositive element?

Cesium is the most electropositive stable element. Francium is more electropositive (at least in theory) but only about 30 grams exists on the entire planet as it is highly radioactive so no one has been able to check.cesium is most electropositive element in periodic table.Ceasium


What is the formula for gallium telluride?

This compound don't exist today. Francium is the most reactive of all the alkali metals, but its chemistry is totally unknown as it is extremely radioactive. Its most stable isotope decay in just 21,8 minutes. So no Francium compounds, as we know them, exist.


How easy is it to cut francium?

Francium is extremely unstable. The most stable isotope of francium has a half-life of only about 22 minutes. Other isotopes of francium have half-lives measured in microseconds. Scientists predict there is less than one ounce of francium in Earth's crust at any one time. Because of this instablilty, it would be much easier to go get a cup of coffee and wait for francium to cut itself apart.

Why is francium uncommon?

- The total quantity of francium in the earth crust is approx. 30 g. - The most stable isotope of francium, 223Fr, has a half life of only 21,8 min. - Obtaining francium artificially by the intermediate of nuclear reactions, is also very difficult and expensive.


What is francium's most abundant isotope?

Francium has no stable isotopes. That means it doesn't really have a "most abundant" isotope; they're all pretty much nonexistent. There are trace amounts of 223Fr in uranium minerals, because it's a decay product of 227Ac (which is itself a decay product in the decay chain of uranium).


The last member of this group all isotopes of this element are radioactive?

The element that fits this criteria is francium (Fr). All isotopes of francium are radioactive, with the most stable isotope having a half-life of only 22 minutes. Francium is a highly unstable element and is very rare in nature.

Did francium's radioactivity play a part in why it took so long to discover?

Francium is a radioactive chemical element; the most known and stable isotope, 223Fr, has a half life of only 21,8 min. It is difficult in this case for francium to accumulate in the earth crust; the total quantity of francium in the earth crust is only ca. 30 g !
