They can also be explained and understood by analyzing the electron configurations of the elements. This is because, elements tend to gain or lose valence electrons to
Periodic Table Review Return to Table of Contents Slide 5 / 130 Periodic Table - Review The periodic table is "periodic" because of certain trends that are seen in the elements. Some of these trends can be seen in the properties of atoms we covered in the last unit: atomic size, ionization energy, electronegativity and metallic character.

Introduction to the Periodic Table, Metals, Nonmetals and Metalloids 2 Dmitri Mendeleev: Father of the Periodic Table Mendeleev organized the periodic table by listing elements in rows by increasing atomic mass. He also put them in groups by reactivity. Mendeleev's table was close to the table we use today.
Objective: To understand trends of the periodic table and practice methods of graphing. Background The Periodic Table is arranged according to the Periodic Law. The Periodic Law states that when elements are arranged in order of increasing atomic number, their physical and chem
Explain how the position of an element in the periodic table is related to the arrangement of electrons in its atoms and its atomic number. Predict possible reactions and reactivity of elements from their positions in the periodic table. 1.2.2 Development of the periodic table State how scientists initially classified elements.
