free since it is a noble gas
Absolutely not. The vast majority are found in a combined state in nature. Iron is not found as metal but always as an ore of mixed oxides etc. The halogens and all group 1,2,3 metals are always found combined etc.
Argon is found in the air! Argon is present if the Earth's atmosphere at 0.94%
Alkali Metals
Yes it can be found in nature in trace amounts in the atmosphere. This is because it is SO UNREACTIVE, it cant possibly be found in compounds.
no. it is not
No , Argon is not component of DNA .It is not a bioelement . It is an inert element and not found in combined state .
Yes! All around you in air!
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.
combined form
Pure boron (a metalloid) is not found in nature. Boron will be combined with something else. Pure boron could be shiny, but will usually be a brown powder when combined with carbon.
Because Xenon is a gas and gases are found uncombined in nature, Xenon is found uncombined.ct

Zinc is usually combined with other elements.
Yes, it is true.
magnesium :)
it is found in airair is made up of oxygen hydrogen, nitrogen, and small amounts of argon.in earths atmosphere
