Fr or Francium is the most reactive alkali metal (group 1)
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.
first group element or group 1 elements are most reactive.beacuse they are alkali metals and contained only 1 electrons in their ns orbital.also their ionisation potential is very low,so they easily lose electron and execute reaction.
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).
As a general rule, these are the elements toward the top of the group in the periodic table.
Most active metals are found on the left side of the periodic table, specifically in groups 1 and 2. These metals have a tendency to lose electrons easily, leading to their reactivity with other elements. Examples include alkali metals like lithium, sodium, and potassium.
In terms of reactivity, Potassium(K) is the most reactive element among group 1 elements.
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.
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.

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.
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).
Francium(Fr) is the most reactive element in Group 1A . The least reactive is Lithium(Li) The element become increasingly reactive 'down' Group 1A. NB You will NOT find francium in a school lab. for two reasons. 1. It explosive when in contact with water. 2. It is 'Radio-active' and radio-active matter has to be kept in special conditions.
As a general rule, these are the elements toward the top of the group in the periodic table.
Lithium (Li) is the easiest element to cut in Group 1 of the periodic table. Being a soft metal, lithium can be easily cut with a knife.
Group 1 is the most active and Group 2 is second.
