CHE 131 Lecture Notes - Alkali Metal, Alkaline Earth Metal, Noble Gas
Document Summary
The periodic table of elements displays a variety of chemicals commonly used in chemistry, physics and other sciences. The periodic table is organized by groups of elements (columns) and periods (rows). There are 8 rows and 18 columns within the period table. The groups within the periodic table are alkali metals, alkaline earth metals, transition metals, post- transition metals, metalloids, halogens, noble metals, and noble gasses. The 7 major groups within the periodic table are alkaline earth metals, alkali metals, transition metals, non metals, halogens, noble gasses and noble metals. The elements within the alkali metal group are lithium, sodium, potassium, rubidium, caesium, and francium. The elements within the alkaline earth metals group are beryllium, magnesium, calcium, strontium, barium, and radium. examples of elements with the transition metals group are cobalt, iron and silver. Examples of elements within the halogen group include fluorine, chlorine and iodine. Examples of elements within the noble metals group are platinum and gold.
