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.
Noble gases, such as helium, neon, and argon, are the least reactive group in the Periodic Table. They have a full outer shell of electrons, making them stable and less likely to form chemical bonds with other elements.
Cesium (Cs) at 0.79 and Francium (Fr) at 0.70 have the lowest electronnegativities in the Periodic Table. Dr. Shaun D. Black University of Texas at Tyler, Department of Chemistry
Noble gases are least reactive because they have a full shell
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 noble gases group (Group 18) on the periodic table would not be reactive chemically. This is because they have a full outer electron shell, making them very stable and unlikely to form chemical bonds with other elements.
The most reactive nonmetal is fluorine. Fluorine is a halogen, which is Group 17 on the Periodic Table, and the halogens are the most reactive...

in the Periodic Table it is the most reactive metals!
Noble gases are the least reactive elements on the periodic table. They have a full outer electron shell, making them stable and unlikely to form chemical bonds with other elements.
Alkali metals. This is the most reactive group on the periodic table
The Alkali metals are the most reactive group of metals in the Periodic Table. Of these Francium is the most reactive metal of all.
Beryllium is the least reactive element in group 2 of the periodic table. It has a strong chemical affinity for oxygen, forming a protective oxide layer that prevents further reactions with air or water.
The Alkali metals are the most reactive group of metals in the Periodic Table. Of these Francium is the most reactive metal of all.
The noble gases group (Group 18) on the periodic table would not be reactive chemically. This is because they have a full outer electron shell, making them very stable and unlikely to form chemical bonds with other elements.
The most reactive metals are in the group 1 of the Periodic Table - the alkali metals.
