A covalent compound.
When a nonmetal oxide reacts with water, it typically forms an acid. The nonmetal oxide will react with water to produce an acidic solution. One common example is sulfur dioxide reacting with water to form sulfurous acid.
It forms acidic solutions
Rusting is an oxydation reaction; in this case oxygen (a nonmetal) react with iron (a metal). Oxygen is a very reactive chemical element.
A nonmetal typically forms covalent bonds with other nonmetals or with metalloids. Nonmetals can also react with metals to form ionic compounds. Additionally, nonmetals can combine with nonmetallic elements to form compounds, such as sulfur combining with oxygen to form sulfur dioxide.
A metal and a nonmetal; but exceptions exist.
Sodium metal can react with the nonmetal chlorine to form sodium chloride, which is a white crystalline compound commonly known as table salt.
According to my chem book, a transfer of one or more electrons from the metal to the nonmetal often occurs
Vinegar (acetic acid) can react with some reactive metals as alkaline metals.
Yes, oxygen is an active nonmetal. It is highly reactive and forms compounds with many elements.
When a nonmetal bonds with another nonmetal, it forms a covalent bond. In this type of bond, atoms share electrons in order to achieve a stable electron configuration. This results in the formation of molecules or compounds, such as water (H2O) or carbon dioxide (CO2).
