The 2nd most reactive is Cesium after Francium.
If you disregard Francium because it is radioactive, then it would be Rubidium after Cesium.
The first is francium, a radioactive metal in the Alkali Metals. The second most reactive metal would be the one right above it, Cesium.
The most reactive non-metal is fluorine. It is often nicknamed the 'Tyrannosaurus Rex' of the elements because of its reactivity. NB . Oxygen ,which we breath, is also a very reactive element. If it wasn't so reactive we would probably die.
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.
Using Electrolysis: is the most powerful extraction method. But it takes a lot of electricity and that makes it expensive. Hence, electrolysis is only used for the most reactive metals.The method of extracting metal from its ore depends upon how reactive the metal is. The more ractive the metal, the more difficult and expensive it is to seperate from its ore.
The rate of corrosion is directly linked to a metal's reactivity. The higher the metal in the series, the more reactive, also more susceptible to corrosion with oxygen and water. aluminum is not easy to corrode. Aluminum quickly reacts with oxygen in the air, and the oxide layer that forms protects the metal underneath from any further reaction.
The most reactive elements have either 1 valence electron or 7 valence electrons
Fluorine is the most reactive non-metal.
caesium is the most reactive non-radioactive metal and Florine is the most reactive non-metal, but francium is the most reactive, radioactive metal
Metals which can easily loose electron are most reactive. They are present in group-1.
Francium (Fr) is the most reactive metal.
Lithium is the most reactive metal found.
Cesium is the most chemically reactive metal.
Francium is the most reactive metal because has the lowest electronegativity.
fluorine is the most reactive non metal in the periodic table.
Radium is the most reactive in this group.
Potassium is not the most reactive, Francium is.
Aluminum is pretty reactive, but it is nowhere near the most reactive.
Francium is the most reactive metal and fluorine the most reactive nonmetal.
