Cesium
The highest reactive element is oxygen.
The three most common reactive elements are oxygen, fluorine, and chlorine. Those elements react so readily with other elements because they have free electrons that can break free of their host atom and attach themselves to another kind of atom in order to form a bond between both. Oxygen is the most reactive because it has eight such electrons (four in its outer shell and four more in its two inner shells) the are quite readily accessible to attack other atoms; fluorine has seven available electrons; chlorine has six.
I hope this helps!
CHEMISTRY OVERLOAD SCENE? DO THOSE REALLY HAPPEN?##
Yes! A sort of chemistry overload scene happens
Caesium is an extremely reactive chemical element.
The most reactive chemical element is fluorine. Reactivity of the elements increases as we go down and to the left on the periodic table, and it also increases as we go up and to the right on the table.
Chlorine is the most reactive gas element. Chlorine is in the halogen family.
Seaborgium is supposed to be as reactive as wolfram.
An element is said to be chemically reactive when it combines with another element. These two elements will create a new compound.
How reactive is the element silicon?
That would be the element with the highest atomic number but the lowest number of valence electrons.
Among the elements listed in the question, potassium, by a large margin, is most reactive.
Fluorine is the most reactive element.
Caesium is an extremely reactive chemical element.
The most reactive chemical element is fluorine. Reactivity of the elements increases as we go down and to the left on the periodic table, and it also increases as we go up and to the right on the table.
The element Californium is reactive.
Hydrogen is not only the lightest element of all, it is also very reactive.
It is the fourth least reactive element, followed by Mercury, Gold and Platinum.
Plutonium is a reactive chemical element.
Fluorine(F2) is the most reactive element, known to react with even Xenon, Krypton, Gold, Platinum, etc.
