If pure argon gas were mixed with pure hydrogen gas would the two elements react with each other?

Answer :

Answer:

No, the two substances will not react with each other

Explanation:

We already know that argon belongs to group 18 in the periodic table. Members of this group are commonly referred to as noble gases. So, we can say that argon is a noble gas.

One characteristic of noble gases is that they possess a filled outermost shell, they have a complete octet of electrons. As a result of this, they hardly  participate in chemical reactions since they have already attained the stability that arises from having a complete octet of electrons.

Hence, argon will not react with hydrogen.
