non-metals
The noble gases.
The noble gases in Group 18 contain elements that are all gases at standard temperature and pressure (STP). Therefore, the period that contains the most elements that are all gases at STP is the third period.
Noble gases (or group 18 elements)
The noble gases.
the most stable element group is the noble gases group
The noble gases (aka inert gases) are the most stable elements.
Noble Gases, Group 8A
The noble gases are the most unreactive family of gases. They have a full outer electron shell, making them very stable and unlikely to form chemical bonds with other elements. This includes gases such as helium, neon, argon, krypton, xenon, and radon.
The Noble Gases Group are called 'noble' because they don't willingly react with anything. The Noble Gases are Group (or Family) 18, the column on the far right side of the periodic chart.
Inert gases, also known as noble gases, are elements that do not react rapidly with other elements because they have a full outer electron shell, making them stable. Examples include helium, neon, and argon.
D - block contains most elements.... ie,from 3rd group to 12th group
Yes, except for the group 18 elements (noble gases), most nonmetals readily form gases due to their high electronegativity and tendency to gain electrons in chemical reactions. This allows them to exist as gases at room temperature and pressure.
