Question

Why are the noble gases more stable than other elements of the periodic table?

Noble gases are more stable than other elements because their valence shells are completely
full.
The noble gases are more stable because they are at the far right of the table.
Noble gases are more stable than other elements because they have larger atomic numbers.
Noble gases are more stable than other elements because their valence shells are empty.

Answer 1

Noble gases are more stable because their valence shells are completely full, making them less likely to react with other elements.

Step-by-step explanation:

The noble gases are more stable than other elements because their valence shells are completely full.

Unlike other elements, such as alkali metals and halogens, noble gases have a full outer electron shell, which makes them less likely to react with other elements. This stability is due to the fact that their valence shells have the maximum number of electrons they can hold. For example, helium has 2 electrons in its valence shell, while neon has 8.

As a result of this full valence shell, noble gases have little to no tendency to gain, lose, or share electrons with other elements, making them chemically inert.
