Question

is argon neutral atom or an ion ? give reason​

Answer 1

Explanation:

Argon is a chemical element with the symbol Ar and atomic number 18. It is in group 18 of the periodic table and is a noble gas. Argon is the third-most abundant gas in the Earth's atmosphere, at 0.934% (9340 ppmv).

Answer 2

It is non-reactive because the shells are full. Argon has three electron shells. The third shell is filled with eight electrons. That is why it does not easily combine with other elements.
