Which of the following elements is usually nonreactive because of its full outer electron shell?
Hereof, what is the name of the family of elements that has a full outer shell of electrons?
The noble gases are a group of elements in the periodic table. They are located to the far right of the periodic table and make up the eighteenth column. Elements in the noble gas family have atoms with a full outer shell of electrons. They are also called the inert gases.
Additionally, which atom is not very reactive since its outer shell of electrons is full?
So much so, that it forms compounds with virtually no other elements. Just like neon (Ne) and helium (He), argon (Ar) usually floats around all by itself. It is non-reactive because the shells are full. Argon has three electron shells.
Chemical Properties of Noble Gases Noble gases are the least reactive of all known elements. That's because with eight valence electrons, their outer energy levels are full. The only exception is helium, which has just two electrons.
