This rare metal has the lowest electronegativity on the periodic table. With an electronegativity number of 0.7 this element donates it's electron very easily to the higher electronegative nonmetals.

∙ 11y agoBecause it can be mutiplyed by the atomic number and is made of of metals so therefore it is the most active....first....Im not exactly shure but I think that's why.

What is the meaning of francium?
Fr is the symbol for the radioactive element francium.
What is the electronegativity difference between fluorine and francium?
The Pauling electronegativity of francium (metal) is 0,7 and the electronegativity of fluorine (nonmetal) is 3,98.
Is francium related to water or caesium?
Francium is an alkali metal, similar to caesium. Water (H2O) is a compound,not an element. Francium, although it is believed to have never been tested, is thought to have been the most reactive element with water. It is among the alkali metals in group 1 on the periodic table of elements.
Whats the most reactive substance?
Quite possibly francium (Fr, atomic number 87) is the most reactive element. Collecting a sample large enough to view is currently impossible, as it would vaporize due to the extreme heat of its decay. The longest isotopic half life of francium is 22 minutes.
What happens when francium and oxygen react?
Francium is a very rare metal that would oxidize very quickly. The word equation is francium + oxygen -> francium hydroxide + hydrogen gas.
What woul the most active metal be?
Francium
Why the francium is the most active metal?
Francium has the greatest electropositivity and the lowest electronegativity.
Why is francium th most active metal?
Francium has the greatest electropositivity and the smallest electronegativity.
Explain why Fluorine is the most active non-metal and Francium is the most active metal?
Francium is the most electropositive chemical element and has the lowest electronegativity; for the fluorine the situation is exactly inverse.
The most active metal would be the one that is?
largest
What is the most active metal besides francium?
The next is caesium.
What element is most active in group 1?
Fr or Francium is the most reactive alkali metal (group 1)
Why the lithium is the most active alkali metal?
Lithium is NOT the most active alkali metal. Francium is the most active but is available in such trace quantities and radioactive that for practical purposes it is Cesium that is considered most active.
Why are francium and fluorine the most active metal and non metal respectively?
Francium has the lowest electronegativity and fluorine the highest.
Where are the most active metal on periodic table?
Francium is the most reactive metal. Reactivity increases and you go down a family and decreases as you go across a period on the Periodic Table. Francium is the farthest left and the lowest so it is the most reactive.
Which element is the most active metal?
The most active metal elements on the periodic table would be Group I. These are the alkali metals which are Lithium, Rubidium, Sodium, Cesium, Francium and Potassium.
Where is the most active metal located on the periodic table Where is the most active nonmetal located?
The most active metal is francium (Fr). It is located farthest to the left and at the bottom. The most active nonmetal is fluorine (F). It is located at the top of Group 17 (the halogens).
