Alkali Metals (group 1) because they only need to lose one electron in order to have a stable valence level of 8. As you go down the alkali metals group, the elements become more reactive. So Francium is the most reactive alkali metal.
Also, Halogens, because they already have 7 electrons and only need to gain one in order to have a stable valence level of 8. As you go up the halogens group, the elements become more reactive. So Fluorine is the most reactive halogen.
This is just a brief summary, if you want to know the reasons why this is I suggest you search about ionization energy, electron affinity, and electronegativity because these are all what make an element "reactive."
What else can I help you with?
Which group are highly reactive non metals on the periodic table?
The halogens are the highly reactive nonmetals on the periodic table. This group includes elements such as fluorine, chlorine, bromine, and iodine, which readily form compounds with other elements due to their strong tendency to gain an electron.
What elements are least reactive on the periodic table?
the noble gases are the least reactive(thats group 18) followed by group 14
What family on the periodic table is the most reactive metals?
The most reactive non-metals are the halogens, group 17.
Which group of elements in the periodic table is known as the alkali?
The group of elements in the periodic table known as the alkali metals is group 1, which includes lithium, sodium, potassium, rubidium, cesium, and francium. These elements are highly reactive and typically form ionic compounds in reactions.
Which element in group 6 is the most reactive?
Elements are more reactive as you go down the periodic table and to the left.
Are the elements on group 17 on the periodic table reactive?
Yes
Which group is more reactive on the periodic table group 1 or 2?
Group 1 elements are more reactive than that of group 2 elements.
Which group on the Periodic Table of Elements has the most reactive nonmetals?
group 17 or halogens
What group of elements on the periodic table is most reactive?
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.
The two most reactive groups of elements in the periodic table are the alkali metals and the what?
The two most reactive groups of elements in the periodic table are the alkali metals and the halogens. Halogens are nonmetals located in group 17 of the periodic table and include elements like fluorine, chlorine, and iodine.
What are the elements in group 8 called on the periodic table?
Halogens these are the salt forming elements which are highly reactive
What are elements called in the periodic table in Group one?
Halogens these are the salt forming elements which are highly reactive
Which group are highly reactive non metals on the periodic table?
The halogens are the highly reactive nonmetals on the periodic table. This group includes elements such as fluorine, chlorine, bromine, and iodine, which readily form compounds with other elements due to their strong tendency to gain an electron.
Are groups 1 and 2 more or less reactive in periodic table?
Group 1 elements are the most reactive among metals, followed by group 2 elements.
Is it true the most chemically reactive metals are in group 1 of the periodic table?
yes the most chemically reactive elements are in group 1
What elements are least reactive on the periodic table?
the noble gases are the least reactive(thats group 18) followed by group 14
What group of elements on the periodic table is most reative?
The alkali metals group, located in Group 1 of the periodic table, is the most reactive group of elements. These elements have one electron in their outermost shell, making them highly reactive as they seek to lose this electron to achieve a stable electronic configuration.
