What electronic structure do most of the noble gases have in common

Noble gases belong to group 18 of the periodic table. These elements are inert because they have their valence orbital shells as ‘full’ hence do not participate in reactions since they cannot share electrons. These elements have a pattern in their electron configuration. Their outer most orbital shells has 8 electrons (with the exception of 2 for helium).

answer:

technetium is the most reactive. this is followed by silver. the least reactive out of these three elements is strontium.
