the noble gases are the least reactive(thats group 18) followed by group 14
These elements are hafnium and zirconium.
its the noble gases that are the least reactive group among the elements; and they occupy the left most group i.e. 18th group in the Periodic Table.
group 1 elements make their hydroxides are highly basic, they are the elements with least ionisation energy
As radioactive element is an element that is on the Priodic Table of Elements. A Radioactive Element is usually radioactive.
talkative
The metals in the lower left corner of the periodic table are the least electronegative.
Group 3, the transition elements.
the least reactive METAL is lithium!!
Sitting on usually indicates you are on something, while at would be near or beside it. So if were on a table, you would be sitting on the table. If you were on a chair beside the table, you would be sitting at the table. Sitting at can also refer to a time something is happening, like: "The parliament is sitting at 2pm".

Noble gases are least reactive because they have a full shell
Hydrogen is the least massive element. It is found in group 1, period 1 on the periodic table.
The noble gases, column 18 or VIII of a periodic table, are the least reactive. However, in the last few decades, compounds of at least the heavier members of this group have in fact been made. Therefore, there is no longer any entire group on the periodic table that is totally unreactive chemically.
Noble gasses (group 8) are the least reactive elements in the periodic table because they have a full valence shell.The right-most column, Group 8*, or the noble gases, is the least reactive elements in the periodic table.* In newer version of periodic table by IUPAC, its the group 18; whereas it was the 8th A group that noble gases occupied in older version.
