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.
Florine is a non-metal. It belongs to the halogen group in the periodic table and is highly reactive, forming compounds with many elements.
metalloids
No. Selenium is a nonmetal belonging to oxygen family.
Chlorine is a non-metal. It is found in group 7 of the periodic table of elements and has electronic configuration [Ne] 3s2 3p5.
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.
no there all metal
By looking at the periodic table of the elements. Carbon is listed as a nonmetal.
Hydrogen is a nonmetal. It is placed in the upper left corner of the periodic table, making it part of the nonmetal group of elements.
Fluorine is a nonmetal. It belongs to the halogen group in the periodic table, which consists of highly reactive nonmetallic elements.
C is a nonmetal. It is found in the upper right portion of the periodic table and typically forms covalent bonds with other elements.
As you move from potassium to krypton in the fourth period of the periodic table, the elements will change from a metal (potassium) to a nonmetal (krypton). Potassium is a metal, while krypton is a noble gas and therefore considered a nonmetal.
For example metal or nonmetal character, radioactivty, atomic weight, reactivity.
elements
Xenon is achemical element and a Non Metal
Elements on the left side of periodic table are metals. The right side elements are non metals and the zigzag line constitutes metalloids.
Florine is a non-metal. It belongs to the halogen group in the periodic table and is highly reactive, forming compounds with many elements.
