Yes, Rn is radon a radioactive nonmetal.
But the symbol Rn does not stand for "radioactive nonmetal."
Rn Radon has no stable isotopes, so yes it is always a radioactive nonmetal.

No, graphite is not radioactive.
No, water is not radioactive.
Yes, it is possible for water to become radioactive if it comes into contact with radioactive materials or is contaminated by radioactive substances.
Some are, some are not.
Rn is radon, a radioactive gas, atomic number 86. It is the product of radium decay.

Isotopes of radon (Rn)
Examples: metals or nonmetals, radioactive or not radioactive, classification after the state of matter, reactive or not reactive etc.
"Rn" on the periodic table stands for Radon. Radon is a radioactive noble gas located in Group 18, Period 6 of the periodic table. It is colorless, odorless, and tasteless, and is produced as a decay product of radioactive elements.
Hydrogen, Oxygen, and krypton are substances that are combinations of nonmetals.
They are all words that have all of the vowels (A, E, I, O, U) in alphabetical order.
The element denoted by Rn 7s25f11 is Lawrencium (Lr), which has an atomic number of 103. It belongs to the actinide series of the periodic table. Lawrencium is a synthetic element and is highly radioactive.
The full form of RN in the periodic table stands for Radon. Radon is a colorless, odorless, and tasteless radioactive noble gas. It is found in trace amounts in the atmosphere and is produced as a decay product of uranium and thorium.
Gaseous nonmetals are: H, O, N, F, Cl, He, Ne, Ar, Kr, Xe, Rn and possible Uuo.
