Inert gases. This was a common term for them until the first reaction between a noble gas and another material was discovered a few decades ago.
Noble gases have completely filled orbitals. They generally have 8 valence electrons (helium has only 2) and obey octet rule (stable electronic configuration). Hence they are chemically inert (or do not react with other elements).
Group 18, also called the noble gases, contains the elements that are nonreactive.
A piece of land that's surrounded by water on three sides is usually called a peninsula.
A peninsula is a region of land surrounded by water on at least three of four sides and connected to a larger piece of land. A sea is a body of water, and thus cannot be called a peninsula.However, seas are usually surrounded by land on three sides, sometimes almost completely surrounded by land, which does make them seem like a water version of a peninsula. There are also inland bodies of water called seas, such as the Dead Sea or Caspian Sea, but these are technically saltwater lakes.
Because the data set is sometimes called a group
Inert Gases
The group 18 elements, also called the noble gases, are gaseous elements, completely nonreactive, with a full, stable valence shell. They were the last elements to be discovered because they're inert.
Noble gases
A body of water almost completely surrounded by water is called an ocean. Oceans will often run into each other.
Helium is a nonreactive element called a noble gas.

That's called a solar eclipse. It can sometimes happen at new moon.

Milk with most of the fat removed is called Skim Milk(sometimes called Skimmed Milk.)
A nonreactive saucepan is one that is made from stainless steel, glass, or ceramic materials. So are those coated with Teflon. They're called nonreactive because these materials in contact with the food don't react with acidic ingredients the way copper and aluminum do. Stainless steel, glass, ceramics and Teflon are highly resistant to chemical attack. And as you might expect, different materials have different advantages and disadvantages.
