All elements in Periodic Table columns 1 - 12 and 17 of a wide form periodic table usually form ionic bonds, as can all other metals and most of the elements in periodic table columns 15 and 16. This does not mean that such elements can not also form covalent bonds.
Those elements which have difference in their electronegativity more than 1.7 form
ionic bonds.
For example, Hydrogen has an electronegativity of 2.1 whereas Fluorine has an electronegativity of 4.0. So, HF(hydrofluoric acid) is an ionic compound.
Ionic Bonds occur with the bonding of MOST metals WITH a non-metal. If it is ONLY NON-METALS, it is a Covalent Bond, and if it is ONLY METALS, it is a metallic bonds. Of course, there are exceptions, so IONIC, COVALENT and METALLIC bonds aren't always formed when they might be expected to be.
Metals form ionic bonds with non-metals. Ionic compounds are always metal/non-metal ions that have chemically bonded.
Metal and non-metals combine together to form ionic bonds.
NaCl tends to form ionic bonds.

Group-14 elements share electrons. they form covalent bonds.

They can form ionic compounds with halogens.

Ionic bonds form between a metal and a non-metal.

They can form ionic compounds with halogens.
Almost every non metal except the elements in group 18 can make ionic bonds with lithium.
Metals forms ionic bonds.

Ionic bonds form between a metal and a non-metal.
The elements in columns 2 and 12 of a wide form periodic table will lose 2 valence electrons when the elements form ionic bonds. (Some other elements also have or can have this property.)
These bonds tend to be ionic. However, all bonds are somewhere between purely ionic and purely covalent.
Because Group 13 elements form both ionic and covalent bonds readily.
Not all ionic bonds are oxidation-reduction reactions. Typically, a metal paired with a nonmetal would form an ionic bond. Ex. Ag+ + Cl- --> AgCl (aq) these atoms are bonded with an ionic bond *All compounds with ionic bonds also have covalent bonding, but to a lesser degree.
The elements that generally form ionic bonds are the metals and nonmetals.
