No, they are both halogens and nonmetals with a electronegativity too close together to form an ionic bond. They, if ever bonded, would form a covalent, or polar covalent bond.
no
It is not ionic, it is covalent.
Lithium
magnesium and fluorine will formthe ionic compound, MgF2
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.
no
Fluorine
yes
It is not ionic, it is covalent.
Yes. They will form the ionic compound magnesium fluoride, MgF2.
Carbon forms covalent bonds with fluorine.
No, they are both halides.
Fluorine is molecular, but it is an element, not a compound.
Lithium
magnesium and fluorine will formthe ionic compound, MgF2
It is AlI3 compound. But it is not ionic.
Potassium will form ionic compound with group 17 elements (fluorine, chlorine, bromine, iodine) and group 16 elements (oxygen, sulphur, selenium).
