noble gasses
Noble Gases
Group-18 family is the most inactive family. It is stable and hence non reactive.
The Noble Gas Family because they have all 8 valance electrons and are therefore stable
It is the noble gas family or the group XVIII.
No, the most stable elements on the periodic table are typically found in the noble gas family. Alkali metals, such as lithium and sodium, are relatively reactive compared to noble gases like helium and neon, which have full valence shells and are therefore more stable.
The noble gases (aka inert gases) are the most stable elements.
The most active metal in the calcium family is francium. It is the least stable alkali metal and can react violently with water, making it extremely rare and highly radioactive.
Tritium is not the most stable isotope known.
stable
Most people remain in the same marriage for their entire married life. Marriage is a very stable way to start a family.
The symbol for the most stable ion of sulfur is S2-.
