The noble gases are a group of chemical elements with very similar properties. A unique feature of this group of elements is that they are known to be very inert or unreactive with other chemicals. What is the best explanation for the low reactivity of these elements?

The noble gases are stable because their outermost (valence) shell of electrons is full. T/F

The given statement is true.

Explanation:

Noble gas elements are present in the group 8th of the periodic table. Noble gases are - He (helium), Ne (neon), Ar (argon), Kr (krypton, Xe (xenon), and Rn (radon). The noble gas is stable because their outermost (valence) electron shell of electrons is full. These elements are the least reactive. Less reactivity of the noble gases is because they did not need to gain or lose electrons to complete their outermost shell.
