The elements in the family Group 0 - Inert Gases (exc. Radon) will not usually combine with other substances, as this group is highly unreactive.
Inert Gases;
Helium
Neon
Argon
Krypton
Xenon
(Radon)
During a single-displacement reaction, one element replaces another in a compound. This reaction is most likely to occur if a more reactive element displaces a less reactive element in the compound. The displacement reaction will result in the formation of a new compound and a free element.
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 (Kr) is the element in group 18 that is most likely to form a compound with fluorine. It can form compounds like KrF2 under extreme conditions.
If you find an element in its pure elemental state in nature, you can infer that the element is likely not very reactive chemically. This is because elements in their pure form tend to have a full outer electron shell, making them stable and less likely to form chemical bonds with other elements.
An element from group 1 (alkali metals) and an element from group 17 (halogens) are most likely to combine to form an ionic compound. For example, sodium (Na) from group 1 can combine with chlorine (Cl) from group 17 to form sodium chloride (NaCl).

Helium is the noble gas least likely to form a compound with another element because it has a full outer electron shell, making it very stable and unreactive.
Presuming that you mean from the left and right of the periodic table, you are likely to get an ionic compound as the left hand (metal) element loses electrons and the right hand (non metal) element gains them.
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.
Sodium is one.
An element such as sodium or potassium would most likely form an ionic compound with sulfur. These metals tend to easily lose electrons to form cations, which can then combine with the sulfur anions to form an ionic bond.
Carbon - the element that defines the chemical word "organic".
Reactive.

Hydrogen fluoride is the most reactive compound in this group (not element).
