Pharmaceutical Analytical Chemistry I (PA101) Lecture 1 Periodic relationships among the elements Periodic table  Periodic table The vertical columns or “Groups" are numbered 1 to 8. "A series" comprises the representative or main group elements "B series" comprises the transition, or subgroup elements.  Periodic table "A series" comprises the representative or main group elements Group 1A metals are called the alkali metals Group 2A metals are called the alkaline earth metal Group 7A elements are called the halogens Group 8A elements are called the rare gases or noble gases  Periodic table Each horizontal row of the periodic table is called a "period" In the sixth and seventh periods two series of elements branch off from group 3B. Elements cerium (Z = 58) to lutetium (Z = 71) are called the lanthanide series, or the rare earth series Elements thorium (Z = 90) to lawrencium (Z = 103) are called the actinide series.  Electron Configuration 1s
