Easy To Use Chart of Periodic Table Trends


Chemistry - Electronegativity, Ionization Energy and Other Periodic Table Trends | - Mr. Causey discusses the importance of electronegativity, ionization energy and atomic radius. Electronegativity is the most important periodic trend and comprehending how it works will help you understand chemical bonding and chemical reactions. |


A brief periodic table trends activity for high school and genchem college students to learn about the 5 trends of the periodic table: ionization energy, electron affinity, metallic character, atomic radius, and electronegativity.

Periodic Table of the Lost Civilization - A Periodic Table Review Game

Do your students REALLY know and understand the periodic properties on the periodic table? In this fun review game, students must decipher the clues to determine the position of each "ancient element" on the periodic table of a lost civilization. How well do your students understand electronegativity, ionization energy, atomic radius, valence electrons, valence shells, periods and families, atomic mass, atomic number, metals, nonmetals and semimetals?

Periodic Trends: Electronegativity; Ionization Energy; and Atomic Radius

This group of activities covers the periodic trends of atomic radius, electronegativity, and ionization energy. In one activity the students measure the atomic radius of several elements going across and down the periodic table. Once the students complete the activity it is easier for them to grasp the periodic trend of atomic radius.

What To Know About Ionization Energy of the Elements

Ionization Energy - Ionization Energy of the Elements. It requires more energy to remove each successive electron. When all valence electrons have been removed, the ionization energy requires becomes more and more. It takes a lot of energy to remove core electrons.


An eerie blue glow and ominous columns of dark dust highlight M78 and other bright reflection nebula in Orion. The dark filamentary dust not only absorbs light, but also reflects the light of several bright blue stars that formed recently in the nebula. Of the two reflection nebulas pictured above, the more famous nebula is M78, in the image center, while NGC 2071 can be seen to its lower left. The same type of scattering that colors the daytime sky further enhances the blue color.
