What element is Group 8 Period 6? It consists of
iron (Fe), ruthenium (Ru), osmium (Os) and hassium (Hs)
.
Where is group 8a on the periodic table?
Despite their name, the noble gases aren’t actually nobility, but they are a group of gases located
on the far right
of the periodic table. The noble gases include helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe) and radon (Rn).
What are the uses of Group 8 elements?
The noble gases are used
to form inert atmospheres, typically for arc welding, to protect specimens, and to deter chemical reactions
. The elements are used in lamps, such as neon lights and krypton headlamps, and in lasers. Helium is used in balloons, for deep-sea diving air tanks, and to cool superconducting magnets.
What are group 6 elements called?
Lr. Group 6A (or VIA) of the periodic table are
the chalcogens
: the nonmetals oxygen (O), sulfur (S), and selenium (Se), the metalloid tellurium (Te), and the metal polonium (Po). The name “chalcogen” means “ore former,” derived from the Greek words chalcos (“ore”) and -gen (“formation”).
Why are Group 8 elements are called noble gases?
These elements are non-reactive and are called noble gases as
they have their outermost orbit complete
.
The first section of Mendeleev’s book dealt with just eight of the known elements —
carbon, hydrogen, oxygen, nitrogen, chlorine, fluorine, bromine and iodine
— and those two strategies worked for those particular elements, according to Michael D.
Germanium
is a hard, grayish white element with a metallic luster. The name of the element is derived from the Latin word for Germany, Germania.
Group 6, numbered by IUPAC style, is a group of elements in the periodic table. Its members are chromium (Cr), molybdenum (Mo),
tungsten (W)
, and seaborgium (Sg).

8th group or 18th group element are called as NOBLE GASES . These are the elements starting from He(Helium) and ending at Og(Ogenesson),they are
least reactive due to their octet electronic configuration
. This property makes them different from other elements of periodic table.
Krypton is used commercially
as a filling gas for energy-saving fluorescent lights
. It is also used in some flash lamps used for high-speed photography. Unlike the lighter gases in its group, it is reactive enough to form some chemical compounds. For example, krypton will react with fluorine to form krypton fluoride.
Group 6 are the
chromium metals, chromium, molybdenum, tungsten
.
zinc group element, any of the four chemical elements that constitute Group 12 (IIb) of the periodic table—namely,
zinc (Zn), cadmium (Cd), mercury (Hg), and copernicium (Cn)
.
(iv) Element
H (Ar)
, is likely to be found in gaseous state at room temperature as it is the 8th element of the group so it would have 8 electrons in its outermost shell which is the electronic configuration of an Nobel gas.
The noble gases (historically also the
inert gases; sometimes referred to as aerogens
) make up a class of chemical elements with similar properties; under standard conditions, they are all odorless, colorless, monatomic gases with very low chemical reactivity.
Features of Modern Periodic Table. There are
eighteen vertical columns known as groups in the modern periodic table which are arranged from left to right and seven horizontal rows which are known as periods
