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, also called the noble gases, contains the elements that are nonreactive.
Group 1 elements are more reactive than that of group 2 elements.
group 17 or halogens
These groups are groups 3 to 12 (transition metals) containing each four chemical elements.
Group 1 in the periodic table is known as the alkali metals group. It includes elements such as lithium, sodium, potassium, rubidium, cesium, and francium. These elements are highly reactive and typically have one electron in their outermost shell.
Group 18, also called the noble gases, contains the elements that are nonreactive.
Group 1 elements are more reactive than that of group 2 elements.
Yes
The group on the periodic table that contains the most reactive nonmetals is Group 17, also known as the halogens. This group includes elements like fluorine, chlorine, bromine, and iodine, which have a strong tendency to gain an electron to achieve a stable electron configuration.
The most reactive goup in the metals is the Alkali metals (Group I) The most reactive non-metal group is Group 17 or VIIA) the Halogens. It is difficult to say which of the two groups is more reactive. Chemists will say that Flourine is the most reactive element. Note that Group 18 is the least reactive, most stable.
group 17 or halogens
These groups are groups 3 to 12 (transition metals) containing each four chemical elements.
Group 3, the transition elements.
Group 1 elements are the most reactive among metals, followed by group 2 elements.
For the most part, the Halogen group is the most reactive group on the periodic table. However, the Alkali metals are just as equal but not quite.
Group 1 in the periodic table is known as the alkali metals group. It includes elements such as lithium, sodium, potassium, rubidium, cesium, and francium. These elements are highly reactive and typically have one electron in their outermost shell.
The first group of the periodic table contains the reactive alkali metals: lithium, sodium, potassium, rubidium, cesium, and francium.
