caesium is the most reactive non-radioactive metal and Florine is the most reactive non-metal, but francium is the most reactive, radioactive metal
Fluorine is classified as a nonmetal. It is a highly reactive, gaseous element that belongs to the halogen group in the periodic table.
Florine is a non-metal. It belongs to the halogen group in the periodic table and is highly reactive, forming compounds with many elements.
No, helium is not both a metal and a nonmetal. The element helium (He), along with its cousins in Group 18 of the periodic table of the elements, is a monatomic nonmetal.
Chlorine is a non-metal. It is found in group 7 of the periodic table of elements and has electronic configuration [Ne] 3s2 3p5.
Yes, selenium is a nonmetal element that belongs to the group of chalcogens in the periodic table. It is not a metal.
Fluorine is classified as a nonmetal. It is a highly reactive, gaseous element that belongs to the halogen group in the periodic table.
Fluorine is a nonmetal. It belongs to the halogen group in the periodic table, which consists of highly reactive nonmetallic elements.
Florine is a non-metal. It belongs to the halogen group in the periodic table and is highly reactive, forming compounds with many elements.
No, helium is not both a metal and a nonmetal. The element helium (He), along with its cousins in Group 18 of the periodic table of the elements, is a monatomic nonmetal.
Chlorine is a non-metal. It is found in group 7 of the periodic table of elements and has electronic configuration [Ne] 3s2 3p5.
Chlorine is a NON-METAL. As STP it is a green gas.
The Alkali metals are the most reactive group of metals in the Periodic Table. Of these Francium is the most reactive metal of all.
Chlorine is a non-metal. It is placed in group-17 of the periodic table.
I take it you mean Sodium? Pure sodium - symbol Na - is a soft, silvery white, highly reactive member of the alkali metals group of the periodic table. So it IS a metal.
Potassium is a metal. It belongs to the alkali metal group on the periodic table.
No. Chlorine is a main group element, but is a nonmetal in the halogen family (group 17).
Yes, very reactive, more than silicon, nitrogen and sulfur (neighbours in Periodic Table. But it is not the most reactive nonmetal, which is fluorine.
