No. If it is written Ar, it is the element Argon. If not, it may be the acronym for a longer-named compound, but it cannot be a chemical formula.

Argon is an element and all the atoms in argon are argon atoms.
The element Argon has 8 Isotopes argon-35, argon-36, argon-37, argon-38, argon-39, argon-40, argon-41 and argon-42.The stable isotopes of argon are:argon-36, 0.34%argon-38, 0.06%argon-40, 99.60%Of the radioactive isotopes argon-39 has the longest halflife at about 260 years, all the others have halflives measured in days or much less.
The chemical symbol Ar stands for Argon. Argon is a colorless, odorless, and inert gas that is commonly used in fluorescent lights and welding operations.

According to wikipedia, argon has 24 known isotopes. 40Ar is most abundant at about 99.6% of natural argon.
Perhaps the electronic configuration of Chromium? Ar for argon, argon has 18 electrons. Electronic configuration of argon can be written as 1s22s22p63s23p6. Electronic configuration of chromium is 1s22s22p63s23p63d54s1. As you can see you can just replace that long chain of figures in front of 3d54s1 with just Ar. Hence, [Ar]3d54s1.
