Two or more elements combined chemically is a compound and the smallest unit is a molecule.
Metal atoms usually lose electrons to form positive ions when they combine chemically with atoms of other elements. This allows them to achieve a more stable electron configuration by attaining a full outer shell.
When they combine chemically, they form compounds, which can have very different chemical properties than the constituent elements.If they are combined physically, they only form mixtures, alloys, or colloids.
Argon is an inert gas and is usually unreactive, so it does not typically combine with other elements or form compounds under normal conditions.
A combination of two or more elements is called a compound. These elements are held together by chemical bonds and can be separated using chemical reaction.
Oxygen and nitrogen are very difficult to combine chemically, often requiring the intense energy of a lightning bolt. When they do they produce chemicals called nitrogen oxides. Usually the reactions produce more than one nitrogen oxide. The most common ones are NO - nitric oxide, NO2 - nitrogen dioxide, and N2O - nitrous oxide. The other nitrogen oxides are N2O3, N2O4 and N2O5, although all three of these are unstable.

No: The compounds more often have very different properties from those of the elements that form them.
They form bonds with other atoms.
When they combine chemically, they form compounds, which can have very different chemical properties than the constituent elements.If they are combined physically, they only form mixtures, alloys, or colloids.
When carbon and oxygen combine chemically, they form carbon dioxide (CO2), which is a colorless gas commonly found in the atmosphere. This process usually occurs during combustion or respiration.
It is because it usually does not combine with any elements
they are 2 completely different substances usually- If they combine they make a compound or a molecule. this is 2 substances together. Example- H2O=Oxygen+2 Hydrogin atoms(water)
They form a compound. The definition is usually two or more elements combined chemically.
Usually Hydrogen and Oxygen but also with other elements to a lesser extent.
Argon is an inert gas and is usually unreactive, so it does not typically combine with other elements or form compounds under normal conditions.
Nominally an atom. However, some element's atoms combine with one another as molecules. For example, carbon is usually extant as C2. In diamonds carbon exists as C4 molecules. Such compounds that exist as elements in different forms are called allotropes.
