Francium has the greatest electropositivity and the lowest electronegativity.
Francium
Francium has the greatest electropositivity and the smallest electronegativity.
The next is caesium.
Fr or Francium is the most reactive alkali metal (group 1)
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.
Francium has the lowest electronegativity and fluorine the highest.
Fluorine is the most active non-metal due to its high electronegativity, which allows it to readily gain an electron to achieve a stable electron configuration. Francium is the most active metal because it has the lowest ionization energy among all the elements, making it highly reactive and prone to losing an electron to form a positive ion.
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.
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.
The most active metal in the calcium family is francium. It is the least stable alkali metal and can react violently with water, making it extremely rare and highly radioactive.
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.
Francium is considered the most active metal as it is at the bottom of Group 1 in the periodic table, making it the most reactive alkali metal. It is highly reactive, and its reactivity increases as you move down the group.
