uninhabited
These elements are hafnium and zirconium.
the noble gases are the least reactive(thats group 18) followed by group 14
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.
The alkali and alkaline earth metals are the least electro negative elements, and the halogens are the most electro negative elements.
Silicon is in Group 14 of the periodic table, which is known as the Carbon Group.
talkative
The metals in the lower left corner of the periodic table are the least electronegative.
Group 3, the transition elements.
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".
Inert/noble gases
Lithium
Noble gases are least reactive because they have a full shell
These elements are hafnium and zirconium.
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.
the noble gases are the least reactive(thats group 18) followed by group 14
The least reactive metal in group 1 of the periodic table is francium. Francium is highly radioactive and has a very short half-life, making it extremely rare and difficult to study its chemical properties.
The Zinc Family also known as group IIB is the second least reactive I believe. The least reactive family is the one with a full p sublevel, the noble gases, the next least reactive would be the family with a full d sublevel. Since group IIB has a full d sublevel, it must be the next least reactive family.
