Question

stable elements of argon​

Answer 1

Explanation:

Argon constitutes 1.288 percent of the atmosphere by weight and 0.934 percent by volume and is found occluded in rocks. Although the stable isotopes argon-36 and argon-38 make up all but a trace of this element in the universe, the third stable isotope, argon-40, makes up 99.60 percent of the argon found on Earth.

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. ... The complete octet (eight electrons) in the outer atomic shell makes argon stable and resistant to bonding with other elements.
