Atoms can combine to achieve an octet of valence electrons by sharing electrons. The term covalent bond is used to describe the bonds in compounds that result from the sharing of one or more pairs of electrons.
Ionic and covalent bonds differ in the extent to which a pair of electrons is shared by the atoms that form the bond. When one of the atoms is much better at drawing electrons toward itself than the other, the bond is ionic.
When the atoms are approximately equal in their ability to draw electrons toward themselves, the atoms share the pair of electrons more or less equally, and the bond is covalent. This where sulfur dioxide fits in.
Sulfur can form both ionic and covalent bonds depending on the elements it is bonding with. When sulfur bonds with a nonmetal, it forms a covalent bond by sharing electrons. When sulfur bonds with a metal, it typically forms an ionic bond by transferring electrons.
Sulfur typically forms covalent bonds in most of its compounds, including hydrogen sulfide (H2S) and sulfur dioxide (SO2). However, in some cases, sulfur can also form ionic bonds, such as in compounds like sodium sulfide (Na2S).
Polar covalent. The difference in electronegtivity is insufficient for an ionic bond
Na2S is an ionic bond. Sodium (Na) is a metal and sulfur (S) is a non-metal, so they form an ionic bond by transferring electrons from sodium to sulfur.
No, calcium and sulfur do not typically form a covalent bond because calcium typically forms ionic bonds by donating its two valence electrons to sulfur, which is a nonmetal. Calcium and sulfur would form an ionic bond in a compound like calcium sulfide (CaS).

Sulfur and oxygen typically form a covalent bond when they combine to create compounds like sulfur dioxide (SO2) or sulfur trioxide (SO3).

Sulfur trifluoride (SF3) does not contain an ionic bond. It is a covalent compound with sulfur sharing electrons with fluorine atoms to form covalent bonds.
Sulfur dioxide (SO2) is a non-metal, oxygen (O) is a non-metal, and a bond between two non-metals is a covalent bond. A covalent bond is a chemical bond that involves sharing a pair of electrons between atoms in a molecule, each atom then attaining the equivalent of the full outer shell necessary for a stable electronic configuration.
Sulfur and oxygen are likely to form covalent bonds rather than ionic bonds due to their similar electronegativities. The compound formed would be acidic in nature because sulfur and oxygen can combine to form acidic oxides, such as sulfur dioxide and sulfur trioxide.
Sulfur and chlorine typically form a covalent bond because they are both nonmetals. In a covalent bond, they share electrons to achieve a stable electron configuration.
