Their valance electrons form an octet.
Each compound wants to have 8 valence electrons (which forms an octet). Groups 1 and 2 have 1 and 2 valence electrons respectively. 16 and 17 have 6 and 7 respectively. So together, they form 8.
Many of the aromatic compounds are not soluble in water, the exceptions are such compounds with polar groups like acid groups, phenolic groups etc.
I am not clear about the answer required here. Elements form molecules. Many compounds form polymers, either naturally or synthetically.
Yes, both. Ring structures are called cyclic compounds and can be aromatic or aliphatic, there are a wide variety of cyclic compounds that can be made/found, such as furan and pyridine (both heterocycles). Functional groups such as OH can also be attached to a cyclic ring. "Chains" are aliphatic and are termed acyclic
Although gold is unreactive, it forms many compounds with a range of oxidation states.
Elements on opposite sides of the periodic table, for example Groups 1 and 17, form ionic compounds. Examples include LiCl, NaCl, KI, and RbBr. The elements in Group 1 are the alkali metals, and the elements in Group 17 are the halogens, which are nonmetals.

A biflavonoid is any of many compounds which contain two flavone groups.

Elements and compounds can combine in different ways.One analogy is the way in which 26 letters of the alphabet used for English can come together to form tens of thousands of words, or the way in which ten digits, and a few symbols can make up all the numbers - infinitely many of them.
Well not many of us know abotthabad neither finalabad but for most of the season we've all known westhamarebad!
No. Many compounds are liquids (water, hexane) and gasses (carbon dioxide, ammonia) at room temperature. Many compounds are solid at room temperature and can, but often do not exist in the form of a powder.
Although gold is unreactive, it forms many compounds with a range of oxidation states.
Yes, uranium can form many compounds with the majority of other elements.
Opposites attract
Silicon can form many compounds. It, like carbon, can bind in many ways with itself and with other chemicals, making a huge number of possible compounds.
