This is to my opinion not very probable, though never say impossible:
Today Mendelejev's Periodic Table looks rather incomplete, there were no 'transition' elements in it (group 3 - 12)
13
Sodium - group 1
Noble gases are found in group 18 of the periodic table.
The three families that are found in the center portion of the periodic table are the Iron group, the Cobalt group and the nickel group. There are 18 families in the periodic table.
Hydrogen is found in group 1 row 1 of the periodic table
Cesium is found in group 1 of the periodic table.
3p6
It is found in group 18 (the group on the extreme right)
13
Sodium - group 1
Noble gases are found in group 18 of the periodic table.

Noble gases are found in the 18th group in the periodic table.
Nitrogen can be found in the 1st period of group 15 elements in the periodic table.
