A metal (as positively charged cations) and a non-metal (as negatively charged anions) need to be held together to form an ionic compound.
Metal and Non-metal
F2 is neither ionic nor a compound, it is an element, fluorine, in the diatomic form.
Fluorine
Yes, the elements potassium and chlorine will react--very vigorously--to form the ionic compound potassium chloride.
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.
Metal and Non-metal
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.

An ionic compound forms when atoms of an element of low electronegativity transfer one or more electrons per atom to atoms of an element of high electronegativity. The resulting cations, formed from the atoms of the element of low electronegativity, and anions, formed from the element of high electronegativity, are held together by mutual electrostatic attractions to form the ionic compound.
Nearly all metals will form ionic compounds with oxygen, or 'oxides', as they are called.
Ionic compounds are formed between metals and non-metals.
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.
