A large variety of periodic tables of the chemical elements have been proposed. It was Mendeleev who proposed a periodic table based on the extensive periodic law and predicted a number of unknown elements at that time. The periodic table currently used worldwide is of a long form pioneered by Werner in

Periodic Table of the Elements
Ionization energy : energy required to remove an electron from a gaseous atom when the atom is in its ground state. Metallic character : the extent to which an element exhibits the physical and chemical properties characteristic of metals, for example, luster, malleability, ductility, and good thermal and electrical conductivity. When they were discovered, their properties were found to closely match those predicted by Mendeleev Henry Moseley discovers concept of atomic numbers. Observed that frequencies of Xrays were different for each element. Was able to arrange these frequencies in order by assigning each element a unique whole number, which he called the atomic number. This is because both 1s shells are the only ones not shielded from the nucleus by other electrons.
7.S: Periodic Properties of the Elements (Summary)
The elements in the periodic table are arranged in order of increasing atomic number. All of these elements display several other trends and we can use the periodic law and table formation to predict their chemical, physical, and atomic properties. Understanding these trends is done by analyzing the elements electron configuration; all elements prefer an octet formation and will gain or lose electrons to form that stable configuration.
These trends can be predicted merely by examing the periodic table and can be explained and understood by analyzing the electron configurations of the elements. Elements tend to gain or lose valence electrons to achieve stable octet formation. In addition to this activity, there are two other important trends.
На мгновение Беккер задумался. Потом изобразил смущенную улыбку. - Неужели это так заметно. - Как ее зовут? - Женщина лукаво подмигнула. - Меган, - сказал он печально.
Порядок, - усмехнулся. Завладеть персональными кодами компьютеров Третьего узла было проще простого.
