Presumably francium -- I don't know whether enough has ever been made to test. Among stable elements, cesium.

What non-metal element is most chemically active?
Hydrogen...
Why the lithium is the most active alkali metal?
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.
Which is the most active element?
fluorine
Is Ca the most active element?
No, it is not. The most reactive element is would be francium. The most reactive element that can be gathered in any appreciable quantity is cesium.
Is Au the most active element?
No. Au (gold) is one of the least active elements.
What non-metal element is most chemically active?
Hydrogen...
Explain why Fluorine is the most active non-metal and Francium is the most active metal?
Francium is the most electropositive chemical element and has the lowest electronegativity; for the fluorine the situation is exactly inverse.
What element in period 4 is the most chemically active non-metal?
Carbon, if not wiki it
Which element is the most active metal?
The most active metal elements on the periodic table would be Group I. These are the alkali metals which are Lithium, Rubidium, Sodium, Cesium, Francium and Potassium.
Is Be the most active element?
No. Be is active, but is nowhere near the most active element.
The first element in a period is always an active?
The first element in a period is an alkali metal.
Which element in period 3 on the periodic table is the most active non metal?
This is chlorine.
Which of these elements is the most chemically active?
Fluorine is sometimes called the hungry wolf of the periodic table because it is the most reactive element.
Is Mg the most active element?
No. while magnesium is a very active element is is far from being the most active.
What must an element be in order to replace another element in a compound?
A metal can displace another metal which is lower in the reactivity series.
What element is most active in group 1?
Fr or Francium is the most reactive alkali metal (group 1)
What active metal is combined to make a salt?
This element is sodium (Na).
