Virion is a virus particle outside the host cell

Detailed explanation-1: -Virus is a non-cellular, obligate parasite that is self-replicative inside a specific host cell. Virion is another form of a virus. The main difference between virus and virion is that virus is the nucleoprotein particle whereas virion is the active, infectious form of the virus.
Detailed explanation-2: -Viruses are nucleoproteins. They are non-cellular structures with infectious genetic material. Virions are capsid-encapsulated viruses with DNA or RNA molecules. It has both nucleic acid as well as protein layers.
Detailed explanation-3: -Introduction. Viruses are obligate intracellular parasites and their reproduction entirely relies on the host cell machinery for the synthesis of viral components such as nucleic acids, proteins and membranes.
Detailed explanation-4: -Viruses are small obligate intracellular parasites, which by definition contain either a RNA or DNA genome surrounded by a protective, virus-coded protein coat. Viruses may be viewed as mobile genetic elements, most probably of cellular origin and characterized by a long co-evolution of virus and host.
Detailed explanation-5: -Viruses are small and relatively simple microbes that cannot grow outside of living cells, that is, they are obligate intracellular parasites (Figure 1).
