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.
Potassium is a metal. It belongs to the alkali metal group on 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.
The Alkali metals are the most reactive group of metals in the Periodic Table. Of these Francium is the most reactive metal of all.
No. Chlorine is a main group element, but is a nonmetal in the halogen family (group 17).
