That would be the element with the highest atomic number but the lowest number of valence electrons.
What else can I help you with?
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
Is chlorine one of the most reactive of all elements?
Chlorine is a Highly reactive element.
Is fluorine the most reactive element in the periodic table?
Yes, fluorine is the most reactive element on the periodic table.
Which of the elements in Group 1 are the most reactive?
it is caesium.
What nonmetals are the most chemically reactive?
Fluorine and oxygen are the most chemically reactive nonmetals. Fluorine is the most reactive nonmetal, readily reacting with almost all other elements, while oxygen is highly reactive and forms compounds with most elements in the periodic table.
What are the most reactive elements on the periodic table?
The alkali metals and the halogens are the most reactive groups and among them, francium and fluorine are the most reactive, especially with each other.
Is chlorine the most or least reactive of all elements?
Neither. Chlorine is among the most highly reactive nonmetal elements, but fluorine and oxygen are even more reactive, as are the heavier alkali and alkaline earth metals.
Which element is non reactive to noble gas?
Most elements are non reactive to noble gases.
The most reactive group of the nonmetals are the?
Halogens among halogens fluorine is most reactive
