Nonmetals and metals
No, ionic compounds typically form between a metal and a nonmetal. When two nonmetals combine, they are more likely to form covalent compounds, where electrons are shared between atoms rather than transferred.

Ionic or metallic compounds do not contain covalent bonds. Ex. Salt (ionic) or steel/iron/lead (metallic)
Covalent bonds usually form between two nonmetals/

It's ionic if it is bonded with hydrogen or other metals, and it's covalent if with other nonmetals, but since bromine is a halogen, it is most likely to form ionic compounds.
Compounds with covalent bonds are generally more dangerous more open flames, because they are more likely to combust. Ionic compounds such as salt usually do not react as nearly much to flame. This results due to the different natures of the bonds.
Molecule. A nonmetal to nonmetal covalent bond. Electronegativity is not variant enough among the nonmetals to form ionic bonds.
Often - yes. the reason they break apart is the hydration energy of the ions- many ionic compounds are soluble in water and dissociate into ions, however there are ionic solids such as CaCO3 which are not soluble. The bonds in covalent compunds are often not broken- for example thise in alkanes. However there are covalent compounds which do react with water and dissolve.
CH4, covalent.
Sulfur oxides are covalent compounds.
Polar covaent bonds are formed when there is a difference in electronegativity between the atoms. Elements such as hlogens, (F, Cl, Br, I) oxygen, nitrogen are quite electronegative, elements which are less electronegative that form covalent bonds include some metals, phosphorus, hydrogen, carbon -- check out the electronegativity table.
