Periodic Table如果对题目有疑问，欢迎来提出你的问题，热心的小伙伴会帮你解答。
In the nuclear model of the atom, the ordinal number of an element in the periodic table receives an extraordinarily simple interpretation. In fact, if the numerical value of the charge on an electron is taken as unity, this ordinal number, which is often called the “atomic number” (q....

The first ionization energy of a component or particle is the energy required to move the most loosely held Electron from one mole of vaporous atoms of the component or atoms to shape one mole of vaporous particles with electric charge +1. The factors influencing the primary ionization energy ...
The periodic table of Mendeleev, initially proposed on the basis of 66 elements, and containing 82 elements at the time of Moseley (1887–1915), describes nowadays 118 elements. The huge challenge of this scientific adventure was, and still is, the development of technologies and methods capable...

The element gallium was discovered four years after the publication of Mendeleev’s table, and its properties matched up remarkably well with eka-aluminum, fitting into the table exactly where he had predicted. This was also the case with the element that followed gallium, which was named ...
