Explanation:
The noble gases, also known as Group 18 elements, are helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). These elements are located in the far right column of the periodic table and have full valence electron shells.
Valence Shell:
The valence shell of an atom refers to the outermost energy level or orbital where electrons are found. For the noble gases, this outermost shell is completely filled with electrons.
Stable Arrangement:
The fact that the valence shell of noble gases is completely filled by electrons makes their arrangement stable. This is because atoms are most stable when their valence shells are full.
Addition or Removal of Electrons:
Due to the stable arrangement of noble gases, it is very difficult to alter this stability by either adding or removing electrons. This is because the addition or removal of electrons would disrupt the full valence shell, causing the atom to become less stable.
Easy to Remove Electrons:
However, it is important to note that while noble gases have a stable arrangement, it is relatively easy to remove electrons from their valence shells. This is because the valence electrons in noble gases are held weakly due to the large atomic size and the shielding effect of inner electron shells. As a result, noble gases are typically chemically inert and do not readily form compounds.
Conclusion:
In conclusion, the valence shells of noble gases are completely filled by electrons, making their arrangement stable. It is very difficult to alter this stability by the addition or removal of electrons. However, it is relatively easy to remove electrons from the valence shells of noble gases due to their weak attraction to the nucleus.
