Plutonium doesn't form "common" compounds in the way that, say, sodium chloride (table salt) or water do. This is because plutonium is a highly radioactive element and its compounds are generally not found in nature.

However, plutonium can form various compounds, some of which are:

Oxides:

* Plutonium dioxide (PuO₂): The most common and stable oxide of plutonium. It is a black, ceramic-like solid that is used as a fuel in nuclear reactors.

* Plutonium trioxide (PuO₃): Less stable than plutonium dioxide.

Halides:

* Plutonium fluoride (PuF₃, PuF₄, PuF₆): Fluorides are particularly important for nuclear applications.

* Plutonium chloride (PuCl₃):

* Plutonium bromide (PuBr₃):

Other Compounds:

* Plutonium nitride (PuN): Used as a fuel in nuclear reactors.

* Plutonium carbide (PuC): Also used as a fuel in nuclear reactors.

* Plutonium hydride (PuH₃):

* Plutonium alloys: Alloys with other metals, such as uranium, are used in nuclear weapons and reactors.

It's important to note that working with plutonium compounds requires specialized facilities and equipment due to the element's high radioactivity and toxicity.
