Kr; Krypton
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
Carbon forms covalent bonds with fluorine.
CF2
Fluorine
yes
Fluorine is the most electronegative element. It can form compounds with almost every element. Some examples are NaF, KF and ClF.
Krypton
You are most likely referring to ClF (with a lowercase L). This compound contains chlorine and fluorine.
Fluorine is similar to chlorine.
