No, they form a covalent compound because there is not a great enough difference in electronegativity for one element to completely pull the electrons away from the other.
no
CF2
Assuming that "flourine" is intended to be "fluorine", the answer is no. Both carbon and fluorine are unlikely to be electron donors and therefore form a covalent bond instead, so that both of these non metals can share electrons.
Krypton (Kr)
Lithium
no
You are most likely referring to ClF (with a lowercase L). This compound contains chlorine and fluorine.
Carbon forms covalent bonds with fluorine.
yes
Fluorine is similar to chlorine.
As the electronegativity difference between phosphorus and fluorine is less than 1.7 according to Pauling's Scale, they cannot form an ionic bond.
CF2
Chlorine (Cl) is the most likely element to form an ionic compound with barium (Ba) due to their opposite charges and high reactivity. Barium typically forms Ba2+ ions, while chlorine forms Cl- ions, allowing them to easily combine to form BaCl2.
Krypton
