Modern Periodic Law: similar properties of the elements occurperiodically when arranged by their atomic (not masses)2. The arrangement of the periodic table is now based on howelectrons fill various energy levels3. Organization:a.Period: horizontal row of elements by increasing atomic number; seven...

indicates the relative ability of its atom to attract electrons. As you move from left to right in a period the electronegativity increases. As you move down in a group the electronegativity decreases. The lower left side of the periodic table has the lowest and the upper right has the ...
The Periodic Table and Periodic Law 6.1 Development of the Modern Periodic Table Objectives Trace the development and identify key features of the periodic table. History of the Periodic Table’s Development In the 1790’s Antoine Lavoisier compiled a list of 33 known elements. The 1800s brought...
The ideal gas law has a lot of facets. This quiz and worksheet will help you check your knowledge of the gas law regarding the different variables of the ideal gas equation, standard units of pressure, and constants in the equation.
I inform you that the periodic table was built by the Russian chemist Dmitry Mendeleev in 1869. He also combined all the ideas into a periodic law in 1871. And Messrs. J.J. Thomson and Ernest Rutherford have only clarified some details and elements of this table. Why don’t you mention...
History of the Periodic Table Moseley and the Periodic Law In 1911, the English scientist Henry Moseley discovered that the elements fit into patterns better when they were arranged according to atomic number, rather than atomic weight The Periodic Law states that the physical and ...
