Group 3, the transition elements.
The metals in the lower left corner of the periodic table are the least electronegative.
These groups are groups 3 to 12 (transition metals) containing each four chemical elements.
That's not a very valid question becase you could argue that all the elements in that particular group are important. There are at least 4 common ones there, which are carbon, silicon, lead, and tin.
These elements are hafnium and zirconium.
Yes, all matter on earth contains at least one element, and all elements are found in the periodic table.
the noble gases are the least reactive(thats group 18) followed by group 14
Noble gases are least reactive because they have a full shell
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.
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 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.
The noble gases, (e.g. Helium) because they don't react because they have full molecular shells. Hydrogen was replaced from Helium in blimps because of this.
Group 18 or Noble gases. As they have completely filled orbitals.
