elements and compounds
Nitrous oxide, commonly known as laughing gas, is a chemical compound with the formula N2O, so it consists of TWO elements: Nitrogen (2 atoms) and Oxygen (1 atom), which are together three ATOMS.

Iron and oxygen are the two elements that combine to create iron oxide. In the case of rust, iron reacts with oxygen in the presence of water to form iron oxide, commonly known as rust.

Iron oxide is composed of iron and oxygen atoms. The most common forms are FeO (iron(II) oxide, or ferrous oxide) and Fe2O3 (iron(III) oxide, or ferric oxide). Iron(II) oxide has a black to brown hue, while iron(III) oxide appears as a reddish-brown color.
No. Mercury is an element and oxygen is an element, but together they form a compound.
