Any metallic element will form an ionic compound with fluorine. ("Flourine" is not a chemical name!) Examples of metals are sodium, magnesium, lanthanum, and iron.
Lithium. Practically every metal combined with fluorine will give you an ionic compound. Some transition metals have volatile penta and hexafluorides and these are bonded with polar covalent bonds.
They would form the ionic compound potassium fluoride, KF.
Helium will not bond with fluorine or any other element.
No, CF2Cl2 is covalent as the the three elements in it (Carbon, Fluorine, and Chlorine) are all nonmetals. Nonmetals form covalent bonds with one another.
A bond between fluorine and sodium would be covalent (non-ionic), as they are both nonmetals, and the difference in their electronegativities is less than 1.7.
If fluorine combines with an element such that their electronegativity difference is more than 1.7, then they will form an ionic compound. Example:- Hydrogen fluoride is an ionic compound. Hydrogen has electronegativity of 2.1 and fluorine has 4.0. So, the difference is 1.9. Therefore, it is an ionic compound.
any element that is a non metal will do
Lithium
The single "most likely" element that would form an ionic compound with fluorine is cesium, or possibly francium if enough of it could be collected. This is because cesium, among stable elements, has the lowest electronegativity and fluorine has the highest electronegativity. However, any alkali or alkaline earth metal element in fact readily forms an ionic compound with fluorine, as do many other metals.
Lithium. Practically every metal combined with fluorine will give you an ionic compound. Some transition metals have volatile penta and hexafluorides and these are bonded with polar covalent bonds.
All of the metallic elements will form an ionic bond with fluorine.
All the alkali and alkaline earth metals: Li, Na, K, Rb, Cs, Fr, Ra, Ba, Sr, Ca, Mg, and Be. Most other metals would also form an ionic compound with fluorine.
They would form the ionic compound potassium fluoride, KF.
They would form an ionic compound.
Helium will not bond with fluorine or any other element.
Metals of group 3,2&1 but most efficiently the group 1 metals b'coz of their large eletronegetivity diff. With fluorine which faciliates them to form ionic bond.
They would form an ionic compound.
