Noble gases group has only non metals.It is group 18 on the periodic table.Noble gases includes helium,neon and xenon.
Group 17 and 18 both contains non metals.Group 17 is called Halogens.Group 18 is called Noble Gases.
Helium is a Noble Gas in Group O.
This is the family of noble gases (group 18).
The Noble Gases-because they rarely combine with other elements and are found only as uncombined elements in nature.
Noble gases group has only non metals.It is group 18 on the periodic table.Noble gases includes helium,neon and xenon.
The first period or row contains only elements that are gases at standard temperature and pressure.
This is the group 18 of the periodic table of Mendeleev.
Periodic column 18 or VIII contains only noble gases. None of them have won a Nobel prize.
The very last group. These have a full set of electrons in their valance shell and will therefore not react easerly. What i mean by very last is the group starting with helium and ending in radon
Group 17 and 18 both contains non metals.Group 17 is called Halogens.Group 18 is called Noble Gases.
Helium is a Noble Gas in Group O.
At a pressure of 1 atmosphere and 20 deg C, only one group (17) contains exactly 2 gases.
As we all know that noble gases are also called INERT GASES, so the subgroup VIII of GROUP 'A' contains only noble gases and inert gases so helium and neon are also in VIII-A so they are inert gases.
There is no method to designate such properties. Only symbols with atomic number are mentioned.
It is the only known element whose atom contains 54 protons. There are other elements in the same group and in the same period, there are other gases, and so on.
