Francium is the most reactive metal. Reactivity increases and you go down a family and decreases as you go across a period on the Periodic Table. Francium is the farthest left and the lowest so it is the most reactive.
The most active metal is francium (Fr). It is located farthest to the left and at the bottom. The most active nonmetal is fluorine (F). It is located at the top of Group 17 (the halogens).
It is fluorine. Fluorine is part of the halogens they are very active nonmetals.
This is chlorine.
Potassium is the most active metal. It is highly reactive and can easily react with water to produce hydrogen gas and caustic potassium hydroxide.
The most chemically active non-metal, and the most reactive element overall, is fluorine. Fluorine has an extremely high electronegativity, meaning that it will remove an electron form almost anything. Therefore, it is amazingly reactive, and it even reacts with glass.

the most active is oxygen
Because most things are made of metal.
Francium is considered the most active metal as it is at the bottom of Group 1 in the periodic table, making it the most reactive alkali metal. It is highly reactive, and its reactivity increases as you move down the group.
Potassium is the most active metal out of the ones listed. It is in Group 1 of the periodic table, which means it readily gives up its outer electron to form positive ions. Copper, lead, and gold are less reactive in comparison.
Francium
Lithium is NOT the most active alkali metal. Francium is the most active but is available in such trace quantities and radioactive that for practical purposes it is Cesium that is considered most active.
