Fluorine.
The ist group elements Alkali metals are most active elements.
Oxygen is the most active nonmetallic element in group 16, also known as the oxygen group or chalcogens. It readily reacts with many elements to form oxides.
In terms of reactivity, Potassium(K) is the most reactive element among group 1 elements.
No. Be is active, but is nowhere near the most active element.
The most active group of nonmetals are those in Group 17, and these are the halogens. The list is headed by fluorine, which is the most reactive element of the group and of the Periodic Table as a whole.
No, calcium (Ca) is not the most active element. The most active elements are typically found in Group 1 of the periodic table, such as sodium (Na) and potassium (K), which readily react with water and air.
Fr or Francium is the most reactive alkali metal (group 1)
No. while magnesium is a very active element is is far from being the most active.
In a single replacement reaction, the element that is most active is the one that is higher up on the reactivity series than the element it is trying to replace. The more active element will displace the less active element in the reaction.

The most active element in Group 17 of the periodic table turns out the be the most reactive element among all of the elements. It's fluorine (F), and we sometimes hear it called the "hungry wolf" of the periodic table because it is so reactive.A link is provided to the Wikipedia post of the periodic table. This table features hyperlinks as part of its makeup. Each chemical element's symbol is a link to the Wikipedia post on that element.
