That would have to be a shared honor. The group on the far right side of the Periodic Table are known as the Noble Gases, because they don't "mix" with the other elements. This is because their outer electron shells are full so they don't form bonds.
However, one of the Nobles, Xenon, can, under some pretty rigorous laboratory conditions, be made to compound with Fluorine, with is the most active element, so perhaps it's only "semi-noble."
The noble gases (aka inert gases) are the most stable elements.
The halogens, which is group 17, are the most reactive non-metals. Oxygen is pretty reactive too, even though it's not a halogen.
Helium would be the element that fits this description. It has a high ionization energy, meaning it requires a lot of energy to remove an electron, and tends to be chemically inactive because its outer electron shell is full.
The Noble Gases Group are called 'noble' because they don't willingly react with anything. The Noble Gases are Group (or Family) 18, the column on the far right side of the periodic chart.
Fluorine, oxygen, chlorine.
yes the most chemically reactive elements are in group 1
Fluorine
Noble gases, such as helium and neon, typically do not combine chemically with other elements due to their stable electron configuration. This stability makes them unlikely to form compounds with other elements.
halogens
The noble gases (aka inert gases) are the most stable elements.
The halogens, which is group 17, are the most reactive non-metals. Oxygen is pretty reactive too, even though it's not a halogen.
Xenon is chemically inactive under STP. But under extreme conditions it reacts with more electronegative elements like fluorine and oxygen to from compounds like XeF2, XeOF4, XeF4, XeF6 etc.
Group-18 family is the most inactive family. It is stable and hence non reactive.
Fluorine is sometimes called the hungry wolf of the periodic table because it is the most reactive element.
Helium would be the element that fits this description. It has a high ionization energy, meaning it requires a lot of energy to remove an electron, and tends to be chemically inactive because its outer electron shell is full.
The most chemically nonmetals are on group 7 of the peridic table e.g:F,CL,BR,I
the vertical column is called group in the periodic table.
