Least reactive to most reactive elements Lithium potassium Rubidium.?
rubidium
Which element is most reactive potassium or iron or alumimum?
Among the elements listed in the question, potassium, by a large margin, is most reactive.
What element is most reactive with sulfur?
Among all non--metalsFlorineis the most reactive.
What happens to the reactivity of elements in a group labeled A as atomic numbers increase across period?
they become more reactive since you are moving from left to right on the periodic table, the elements in group 17 are the most reactive.
What groups of metals is the most active?
The first cloumn in the periodic table has the most reactive elements. The elements decrease in reactivity as you go across the table. in other words alkali metals
What are the non-reactive and reactive elements in periodic table?
Noble gases (group 18) are the almost nonreactive elements. Group 1 elements are the most reactive metals. Group 17 elements are the most reactive non-metals.
What gas is the most reactive of all elements?
Francium is the most reactive metal and fluorine the most reactive nonmetal.
Why group 12 is more reactive?
The elements from the group 12 are not the most reactive chemical elements.
Which elements of the halogen family is the most reactive nonmetal?
The most reactive nonmetal is fluorine
What is the pale yellow gas considered the most reactive of all elements?
The halogen gas that is that most reactive of all elements is Fluorine
Least reactive to most reactive elements Lithium potassium Rubidium.?
rubidium
What groups are the very reactive elements from?
there are alkali metals that are the most reactive metals on the periodic table and halogens which are the most reactive nonmetals
Is chlorine one of the most reactive of all elements?
Chlorine is a Highly reactive element.
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.
Which category is the most reactive on the periodic table?
Alkali metals and halogens.
Is fluorine the most reactive element in the periodic table?
Yes, fluorine is the most reactive element on the periodic table.
Where are the most reactive element found on the periodic table?
Group 1, or the alkali metals, left of the table and Group 17, the halogens, right of the table are the most reactive groups. Fr, or Francium (atomic number 87) is the most reactive metal- and fluorine the most reactive halogen. Francium and fluorine would react together explosively they are so reactive.
