We reconsider, in this work, the construction of the two-dimensional (2-D) periodic table. The two-dimensional logarithmic Coulomb system is used to generate atomic shells for the 2-D atoms. A q-deformed model is developed to explain the ordering of the shells predicted by the 2-D ...
Theperiodic tableof elements is arranged based on a series of regular polyhedron. 指出元素周期表的排列规则来自正多面体. 期刊摘选 The size of atoms decreases from left to right across a period in theperiodic table. 在周期表中沿着周期从左到右原子的半径递减. ...
In the periodic table, the elements are placed into a certain period and group based on electronic configurations that originate from the Pauli and Aufbau principles for the electrons surrounding a positively charged nucleus. This order enables us to approximately predict the chemical and physical ...

Periodic table, in chemistry, the organized array of all the chemical elements in order of increasing atomic number. When the elements are thus arranged, there is a recurring pattern called the ‘periodic law’ in their properties, in which elements in t
units (amu). Even though each atom has roughly a whole number of atomic mass units, you will notice that the atomic mass on the periodic table is a decimal; that's because the number is a weighted average of the various naturally-occurring isotopes of an element based on their abundance....
