The Group 1 , Alkali metals.
They all react with oxygen and water to form the hydroxide and release hydrogen.
They all react with oxygen and water to form the hydroxide and release hydrogen.
The reactivity increases down the Group . Lithium gently effervesces. Sodium 'pop's and sparks. Potassium ignites with a bang. Rubidium is moderately explosive. Caesium is violently explosive. Francium is extremely violently explosive. Francium is not reacted in an open laboratory because it is also radio-active.
All the metals in Group 1 are kept under oil; no oxygen present).

∙ 12y agoAlkali metals are the most reactive metals (group 1). Alkaline earth metals are in a close second (group 2) As you go along, the elements become less reactive. The least reactive group is the noble gases (group 18).

Which family of elements are the most reactive metals?
Alkali metals in the first group compose the most reactive family of metals.
Which family of elements is the most reactive nonmetal family?
The most reactive family of nonmetals is the halogen family.
Elements in the second group have 2 outer shell electrons and are also very reactive They are called?
Elements in the second group have 2 outer shell electrons and also very reactive. What are they called?
Most reactive non metal element?
I would easily say that Fluorine is the most reactive element in the world. Fluorine is the most electronegative of all elements and will react with all elements. It is so reactive that it cannot be found alone in nature.
Elements in the same family have similar what?
Elements in the same family-assuming family means classifications such as non-metals, metals-have similar properties.
Whaat is an extremely reactive family of elements?
halogenes
Which elements of the halogen family is the most reactive nonmetal?
The most reactive nonmetal is fluorine
In what group are elements extremely reactive nonmetal's?
Halogens, group 17 (7)
What family is non reactive?
The noble gases are the least reactive among all chemical elements.
Why are the elements Na and Cl2 extremely dangerous?
because they are both highly reactive elements so they will react with anything.
What is the most non-reactive family?
The noble gases are the least reactive among all chemical elements.
How reactive are the elements in group 18?
The elements in group 18 are extremely reactive and re reffered to as the noble gases********************2nd Opinion ******************The elements in group 18 are extremelyun-reactive.
Which elements are most likely to react with other elements?
The elements in Group 1 of the Periodic Table are highly reactive in water, and, only slightly less reactive in Oxygen. Group 2 elements are also quite reactive in Oxygen, but not quite as reactive as those elements in Group 1.
A family of elements that contains the most reactive metals is the?
alkali metals
What is the highly reactive family of elements with 7 valence electrons.?
halogen
What is highly reactive family of elements with 7 valence electrons?
halogen
Which periodic table family consists of highly-reactive elements?
S block has the most reactive elements. The groups 1 and 2 belongs to the s block.
