C and N
Examples: oxygen, sulfur, carbon, phosphorus etc.
Slicon
The most reactive elements are alkali metals and halogens.
The noble gases.
Most polyatomic ions have a negative charge. There are only 2 positive polyatomic ions; Mercury(I) ion and Ammonium ion. False.
Non-metal elements like carbon and oxygen are most likely to form covalent bonds due to their similar electronegativities. Additionally, elements that are close to each other on the periodic table are more likely to form covalent bonds.
Examples: oxygen, sulfur, carbon, phosphorus etc.
Elements that are close to each other on the periodic table typically form nonpolar covalent bonds, as they have similar electronegativities. Some examples of pairs of elements that would most likely form nonpolar covalent bonds include carbon-carbon (C-C), hydrogen-hydrogen (H-H), and chlorine-chlorine (Cl-Cl).
Yes, with itself in the diatomic molecule O2, in many polyatomic anions, and in oxides with most nonmetallic elements.
No. Most polyatomic ions are anions.
During mating season they are most likely to be seen in pairs. other then that they roam alone

An example of elements that would most likely form a polar covalent bond are hydrogen and fluorine. Fluorine is much more electronegative than hydrogen, so it will pull more strongly on the shared electrons, creating a partial negative charge on the fluorine and a partial positive charge on the hydrogen.
A binary compound is a chemical compound made up solely of 2 elements, for example P2O5, Na2O KCl. (The bonding is not relevant- it could be covalent or ionic.)A polyatomic ion is a cation or anion that contains more than one atom. Most contain 2 different elements. For examplepolyatomic anions:- [SO4]2-, [NO3]-polyatomic cation:-[ NH4]+ , [Hg2]2+
Elements with a large difference in electronegativity are most likely to form ionic compounds. For example, metals like sodium (Na) and non-metals like chlorine (Cl) are likely to form an ionic compound due to the large difference in electronegativity.
Elements that are on opposite ends of the periodic table are most likely to form ionic compounds, such as metals and nonmetals. For example, sodium (metal) and chlorine (nonmetal) form the ionic compound sodium chloride (table salt).
In most of the cases it is true but SCN- , Transition metals complex ions and some organic poly atomic ions do not contain oxygen.
