Cesium, rubidium and francium have very little commercial value and thus are not likely to be encountered by the average fire fighter. However, sodium, potassium and lithium have many industrial uses. Sodium, a silvery bright metal, is the most common of the alkali metals and it is produced by the ton.
Francium is a rare element, and the most stable isotope has a half-life of only twenty-two minutes. It has been estimated that only a few dozen grams of Francium can ever be found in Earth's crust at any one time. Due to this incredible rarity, there was a hole in the periodic table below Cesium and to the left ...

On the left is francium (Fr), which has a single valence (or outer) electron. On the right is fluorine (F), which is has seven of eight maximum valence electrons. Fluorine is very reactive for this reason— it's looking to bond with any spare electron it can — and atoms with single outer electrons are most likely to ...
Both cesium and francium will melt in your hand, but they are so chemically reactive that in the presence of water, oxygen or carbon dioxide they react immediately. So this would need to be done in a completely inert atmosphere. And it's still a pretty bad idea. Although under these conditions, they will not ...
Nihonium was synthesized by the RIKEN Nishina Center for Accelerator-Based Science and is the first element discovered in an Asian country. Four other countries have elements named after them: francium for France, germanium for Germany, polonium for Poland, and americium for the United States.
Switching out the fiery tension of the original for lush refrain, the piano session rendition of 'Francium' amplifies the beauty that Grumble Bee threads throughout his music. 'Disconnect' was written at the beginning of 2014 and recorded in Portland, USA with Kris Cummet (Sleeping With Sirens, Issues, ...

Take, for instance, francium (atomic number 87) and astatine (atomic number 85). As Sam Kean, author of a book about the periodic table called The Disappearing Spoon, wrote of those elements: "If you had a million atoms of the longest-lived type of astatine, half of them would disintegrate in 400 minutes.
It is evident in entries like francium, germanium, scandium, polonium, europium, californium, berkelium and americium. But now, for the first time, researchers in Asia will make an addition to chemistry's most fundamental catalog. Scientists from the Riken institute in Japan will bestow an official name on ...
By adding cesium chloride, Perey coaxed the actinium to form crystals; then, through a series of meticulous tests, she laid down the proof that this radiation was something new. Like her mentor, she had discovered an element, which she named francium, in honor of her country. But the story of Marguerite ...
Francium is both the heaviest of the known alkali metals and the most unstable of the first 101 elements in the Periodic Table. Additionally, it has the highest equivalent weight of any element. Francium's chemical properties most resemble cesium. [See Periodic Table of the Elements]. There are 33 ...
Rarer than any metal, any mineral, so rare that if you scan the entire earth, all six million billion billion kilos or 13,000,000,000,000,000,000,000,000 pounds of our planet, you would find only one ounce of it? What is so rare it has never been seen directly, because if you could get enough of it together, ...
Cesium is an alkali metal, along with lithium, sodium, potassium, rubidium and francium. Alkali metals are highly reactive, have one electron in their outer shell, and do not occur freely in nature, according to ChemicalElements. These metals are also very malleable, ductile and good heat and electrical ...
In September 2012 an experiment at the TRIUMF accelerator complex reached a milestone. The FrPNC collaboration —-short hand for Francium Parity Non-conservation—-succeeded in trapping several kinds of francium, including the isotope Fr-207, which had never before been trapped. There is less ...
