It is fluorine. Fluorine is part of the halogens they are very active nonmetals.
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).
This is chlorine.
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 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.
Francium
Because most things are made of metal.
There are a large number of metals present on periodic table. So they are most abundant.
This element is francium in the first group of periodic table.
The number one element on the periodic table is hydrogen. It is not a metal, but the lightest and most abundant element in the universe.
Yes
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 active metals are at the top of the table, and the least active ones are at the bottom. Manganese, copper, and zinc are all examples of the most active metals, and each metal is able to displace the elements below it from a solution.
