The first four are (in order of increasing number / mass:
He = Helium, Ne = Neon, Ar = Argon, Kr = Krypton
Xe = Xenon and Ra = Radon are the other two noble gases

What is the first member of the noble gases?
Helium
Were noble gases shown in the periodic table of 1869?
No, noble gases were not shown in the periodic table of 1869 because they were not discovered until late 19th and early 20th centuries. Helium was the first noble gas to be discovered in 1895, followed by other noble gases such as neon, argon, krypton, and xenon.
What are two noble gases that doesn't reacts with anything?
That should be the first two noble gases: Helium and Neon. These two are chemically inert and do not react with anything.
What are the nonmetals in nobel gases?
There are no metals in noble gases.All are gases in noble gases.
What element is a noble gas in the first energy level?
There are no noble gases in the first energy level. Noble gases are found in the last (highest) energy level of an atom. The first energy level can only hold a maximum of 2 electrons, while the noble gases have completely filled outermost energy levels.
What were noble gases first called?
inert gases

Phase of matter for noble gases?
All noble gases are gases in their standard state

Is He a noble gas?
"He" is not a noble gas. Noble gases are a group of chemical elements on the periodic table that are very stable and non-reactive. Examples include helium, neon, and argon.
Helium neon argon or krypton what are they called?
They are called noble gases.
