Where is the most active metal located on the periodic table Where is the most active nonmetal located?
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).
What is second period at the bottom of the periodic table called?
The first period is at the top of the table. It consists of hydrogen and helium. The bottom period is period 7.
Most active metals are found where in the periodic table?
The most active elements are in group one and two on the periodic table and are always found in nature combined with other elements. The most active metals are in group one, which is the alkali metals, they wouldn't be in group two. (if you need more information) http://www.chem4kids.com/files/elem_alkalimetal.HTML
