Since you're talking about 'gases' I'll assume you mean GROUP 18, which is assigned to the group of noble gases (was formerly -bef. 1960- known as group 81)cf. note)
1) Note:
Nowadays group 8 is assigned to one of the ten groups of transition metals: especially this one to Iron, Rubidium and Osmium. These are not gases at all.

Iron is placed in group-8 in the periodic table. Its symbol is Fe.
It is group 8.
Iron is Period 4 going horozontal on the periodic table.
Group 8 a doesn't exist.
Hassium is in the group 8 of the periodic table of Mendeleev.
Iron is located in Group 8 (VIII) on the periodic table, also known as the Transition Metals group.
Each group/family on the periodic table can determine valence electrons by the last number of the group/family number, like helium. It's a noble gas that has 8 valence electrons because it's on the 18 family/group
The group name for iron is the transition metal group which includes elements found in Group 8 of the periodic table. Iron is found in Group 8 and Period 4 in the periodic table, with the chemical symbol Fe.
There are 8 elements in the third period of periodic table. The elements belong to group-1,2,13,14,15,16,17 and 18
oxygen is in group 16 period 8
tenth column group 8
