  2. Isotopes and their Abundances Mendeleev the Founder of Periodic Table → Mendeleev constructed a periodic table as part of his effort to systemize chemistry. Edgar Fahs Smith Collection, University of Pennsylvania Library Chemistry 120 Online LA Tech Chapter 3-5 Chemistry 120 Online LA Tech Chapter 3-6 Modern Periodic Table Very Long form of Periodic table The periodic table of the elements is a graphical way to show relationships among the elements. In this periodic table, elements 58 through 71 and 90 through 103 are shown in their proper positions. Chemistry 120 Online LA Tech Chapter 3-7 Chemistry 120 Online LA Tech Chapter 3-8 2

Atomic Orbitals in a Sub-Shell p- atomic Orbitals and their Orientation in Space An s orbital has spherical shape; a p orbital has two lobes; a d orbital has four lobes; and an f orbital has eight lobes. Orbitals within a subshell differ mainly in orientation.
