Question

12. Why 18th group elements are referred as inert gases
O Incomplete orbitals
O empty
completely filled orbitals
O partly filled orbitals​

Answer 1

Answer:

completely filled orbitals

Explanation:

The noble gases (Group 18) are located in the far right of the periodic table and were previously referred to as the "inert gases" due to the fact that their filled valence shells (octets) make them extremely nonreactive. The noble gases were characterized relatively late compared to other element groups

Answer 2

Answer:

completely filled orbitals

Explanation:

18th group of elements are referred as inert or noble gases. They mostly do not react with other elements as their last orbit is completely filled with 8 electrons. Examples are Helium, Argon, Xenon, and etc...
