yes - chlorate, hypochlorite, etc etc etc.
No, oxygen and chlorine do not typically form an ionic bond. They are more likely to form covalent bonds, where they share electrons rather than transferring them.
No, oxygen and chlorine are not ionic compounds. Oxygen and chlorine are nonmetals and tend to form covalent bonds rather than ionic bonds. In covalent bonds, atoms share electrons, while in ionic bonds, one atom transfers electrons to another.
Oxygen does not form a covalent bond with chloride, but oxygen does form covalent bonds with chlorine in the polyatomic ions perchlorate (ClO4-1), chlorate (ClO3-1), chlorite (ClO2-1), and hypochlorite (ClO-1).
Among the elements listed, silicon is most likely to form covalent bonds. (Silicon is in the same periodic table column as carbon, which is the most likely of all atoms to form covalent bonds.)
silcon has the lowest electronegtaivity so would most likely form covalent bonds. Sulfur is next (although with group1 and 2 metals it forms ionic compounds) oxygen and chlorine have high electronegativites so form many ionic compounds - however they also form covalent compunds as well.
Chlorine forms covalent bonds with other nonmetals and ionic bonds with metals.
POCl3 is a covalent molecule. It is composed of nonmetal atoms (phosphorus, oxygen, and chlorine) that share electrons to form covalent bonds.
Atoms on the Right Hand Side of the periodic table - Carbon, Phosphorous, Chlorine itself etc
The two most common compounds of oxygen forming covalent bonds are water, and carbon dioxide. However, there are many more.
Hydrogen.
No. Chlorine an oxygen will form covalent compounds.
Carbon will form four covalent bonds, nitrogen will form three covalent bonds, oxygen will form two covalent bonds, and hydrogen will form one covalent bond. Click on the related link to see a diagram showing the structure of an amino acid.
