Group 0 elements are also known as NOBLE gases. Noble gases are...
A. semi-reactive
B. inert
C. highly reactive
D. flammable
Answer (2)
Noble gases are known as inert gases because they do not readily react with other elements due to having a complete outer electron shell. The correct answer to the question is B. inert. They are commonly used for applications where non-reactivity is required, such as in balloons and light bulbs.

The group 0 elements, also known as noble gases, are a group of elements in the periodic table that includes helium, neon, argon, krypton, xenon, and radon.
These gases are called 'noble' because they are typically inert, which means they are very stable and do not react readily with other elements. This is because noble gases have a complete valence shell of electrons, which makes them highly stable and unlikely to participate in chemical reactions under normal conditions.
Therefore, the correct option is (B) inert .
Here's a little more detail about why noble gases are inert:
Electron Configuration : Noble gases have a full set of electrons in their outermost shell. For example, helium has 2 electrons in its only energy level, making it complete. Similarly, neon has 8 electrons in its outer shell. This full valence shell prevents them from forming chemical bonds easily.
Stability : Because of their full outer electron shells, noble gases are already in a stable state, which minimizes their tendency to gain, lose, or share electrons.
Applications : Due to their inert nature, noble gases are used in various applications such as neon lights, helium balloons, and as protective environments for chemical reactions that cannot tolerate air.
The understanding of why noble gases are inert is fundamental in chemistry, helping us predict how elements will behave in various reactions and applications.
