Noble gasses are 'unreactive'; they do not react chemically with other elements. This is due to the fact that their outer electron shells are full, which means that the atoms of these elements are naturally stable. They do not need to react chemically to gain or lose electrons in order to become stable.
Noble gasses are, as the name suggests, gasses at room temperature (on Earth).

What are characteristic of helium?
It is a colorless, odorless, tasteless, nontoxic, and nearly inert gas that heads the noble gas series in the Periodic Table
What is an important characteristic of neon?
Neon is a noble gas placed in the group 18 of the periodic table of Mendeleev.
What is an unusual characteristic of Krypton?
it is a monatomic gas, and it being a noble gas, it does not usually combine with other elements. Although under certain conditions noble gasses are used in Excimer Lasers, such as Krypton Fluoride.
Is incomplete number of electrons is a characteristic of noble gas?
No. The noble gases are largely nonreactive because their outermost energy levels are complete, making them stable by themselves.
Is krypton halogen noble gas or neither?
No, it is a noble gas

Radon is a noble gas and is radioactive.
Is radon thick?
Radon is a noble gas. In general gases are considered thin/low viscosity.
