Because they have the same number of valency electrons , which is 8 , and the same "Inert" chemical properties .
Neon is the second in the Noble Gases group or Group XVIII (18)
The so-called noble or inert gases are in Group 18, the last group on the right of the periodic table of the elements.
No. noble gases are group VIIIA or group 18 elements
This is the family of noble gases (group 18).
group 18 elements are known as noble gases.
No. Halogens are group 17 elements. Noble gases are group 18 elements.
Neon is the second in the Noble Gases group or Group XVIII (18)
The so-called noble or inert gases are in Group 18, the last group on the right of the periodic table of the elements.
No. noble gases are group VIIIA or group 18 elements
This is the family of noble gases (group 18).
Group 17 elements are called halogens, which include fluorine, chlorine, bromine, iodine, and astatine. Group 18 elements are called noble gases, which include helium, neon, argon, krypton, xenon, and radon.
Xenon belongs to the noble gases group in the periodic table.
Noble gases are placed in the group 18 of the periodic table of Mendeleev.
group 18 elements are known as noble gases.
Group-17 is the nearest neighbor to the noble gases in the periodic table.
I - Alkali Metals II - Earth Alkali Metals III - Boron Group IV - Carbon Group V - Nitrogen Group VI - Chalcogenes VII - Halogenes VIII - Noble Gases
Because all noble gases have completely filled valence orbitals. Helium has 2 valence electrons whereas all other noble gases have 8 valence electrons.
