Fluorine
Metal and Non-metal
F2 is neither ionic nor a compound, it is an element, fluorine, in the diatomic form.
Yes, the elements potassium and chlorine will react--very vigorously--to form the ionic compound potassium chloride.
Yes. cesium chloride is ionic
Chlorine (Cl2) is not an ionic compound. It is a covalently bonded element. Chlorine can form ionic compounds like NaCl (Sodium Chloride) or CaCl2 (Calcium Chloride) but is not itself an ionic compound.
Lithium
Metal and Non-metal
Metals form ionic compounds with non metals. Fe is a metal. So it is likely to make ionic bonds with Cl.
Ca (calcium) is an element, not a compound. and it can only form ionic compounds.
It is the form of the element chlorine with a suffix to show that it is in a ionic compound.
F2 is neither ionic nor a compound, it is an element, fluorine, in the diatomic form.
Yes. They will form the ionic compound magnesium fluoride, MgF2.
A metal and a non-metal bond to form an ionic compound.
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.
Yes, the elements potassium and chlorine will react--very vigorously--to form the ionic compound potassium chloride.
Yes. cesium chloride is ionic
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.
