A covalent bond is a special kind of bond in witch a pare of electrons is shared by two atoms. The most common ones in the human body is H2O, and in DNA (C221H282ClN82O133P22).
Carbon is the element tht will form only covalent compound.
Oxygen is an element. It forms chemical bonds with another oxygen atom, forming a nonpolar covalent bond. It forms covalent bonds with other nonmetals, and ionic bonds with metals.
In its pure form as an element, antimony (Sb) is a metal, and it therefore forms a metallic bond rather than a covalent bond.

Metals form generally forms ionic bonds as in salts.Carbon form covalent bonds, for ex.

As a nonmetal carbon forms covalent bonds.
Fluorine forms both ionic bonds and covalent bonds, the former being more common.
No single element can form a bond. Only 2 or more elements can form bonds. Polar bonds occur when there is a dipole moment, or there is asymmetry in the structure. For example, HF forms a polar covalent bond.
Typically the non metals form covalent bonds. Of course some non metals will also form anions when they react with metals. Some metals can also can form covalent bonds however as their electronegativity is low these bonds are often polar covalent
covalent bonds
Rubidium by itself is neither ionic nor covalent. When it forms bonds with other elements, it forms ionic bonds.
Carbon typically forms covalent bonds. It is rare for it to form ionic bonds.
