radioactive decay
Over 99.999% of argon is not radioactive. A trace of radioactive argon-39 can be found in nature, but it is not significant. Synthetic radioactive isotopes of argon exist, as they do for all elements.
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.
Its nucleus emits radioactive particles continuously.
You build it.
at cassy's model and art compannies or i will build a model for you
You can build a model airplane, model auto or an arrow.
Need serial # for build date & location, not model #.
With model wood!
Not unless you build the model.
No. The Model A began in 1927.
How do you build a working model of science and technology for games and sports?
you can build it out of anything if you are smart
well you would just build it
With a hammer
