Answer; 
-Noble gases or Group 18 elements 
Explanation;
A full valence shell is the most stable electron configuration. Group 18 elements or noble gases such as helium, neon, and argon, have a full outer, or valence, shell. Elements in other groups have partially-filled valence shells and gain or lose electrons to achieve a stable electron configuration.
They are extremely unreactive and do not form bonds with themselves. Solid helium is the the ultimate fine powder being monotomic.

Answer:
Names are universal
Explanation:
Current naming system that is followed all over the world is called binomial nomenclature. There are many significant and useful features of this classification system however one of the most important feature is the universality of the name.
The scientific names of organism are usually Latin derived and composed of two  parts  among which first is genus name and second is specie name. 
For example<u>: Rosa indica</u> is the scientific name of Rose and it is same all over the world. Unlike common names we dont have to search for name to make others understand which flower we are talking about because if we know scientific name anyone can understand it.
Hope it help!
