Classification of Elements and Periodicity in Properties
Classification of Elements and Periodicity in Properties July 29, 2024 by Shivbalak Tiwari The classification of elements and the periodicity in their properties are foundational concepts in chemistry, encapsulated in the periodic table of elements. Here’s an overview: Classification of Elements Metals, Nonmetals, and Metalloids : Metals : Generally located on the left side and in the center of the periodic table. They are shiny, conductive, malleable, and ductile. Examples include iron, gold, and copper. Nonmetals : Found on the right side of the periodic table. They are usually not conductive, brittle in solid form, and have more varied physical properties. Examples include oxygen, sulfur, and chlorine. Metalloids : Located along the zigzag line (staircase) on the periodic table. They have properties intermediate between metals and nonmetals. Examples include silicon and arsenic. Groups and Periods : Groups : Vertical columns in the periodic table. Elements in the same gr...
