A.VERIFIED ANSWERfact-checked by tutors
Noble gases (Group 18 elements) are generally unreactive because they have a complete outermost electron shell (an octet, or a duet for Helium). This stable electron configuration makes them chemically inert, as they have little tendency to gain, lose, or share electrons to form chemical bonds.
