This wiki began circa 2013 by User:PlanetStar? When we made the Obamium page, it ended up getting featured in one of the Obamium memes? Mumbaia has tons of stable isotopes, even though it has such a high atomic number? Elements such as Enneaneganeutronium, known as "polyrotalies", can...
The elements in the periodic table are arranged in order of___. A. atomic number B. mass number C. atomic weight D. electron configuration 相关知识点: 试题来源: 解析 A。元素周期表中的元素是按照原子序数排列的。选项 B 质量数、选项 C 原子量和选项 D 电子构型都不是元素周期表排列的主要依据...
In modern form, the law states that the properties of the elements are periodic functions of their atomic numbers. In other words, when the elements are listed in order of increasing atomic number, elements having closely similar properties will fall at definite intervals along the list. Thus ...

Located right above the Englishname for each element, the largest letters represent itschemical abbreviation. The largest number is the element’satomic number. Other information in the box includes the element’s electron configuration, electronegativity, oxidation states, and its first ionization energy...
Then in 1869, as a result of an extensive correlation of the properties and the atomic weights of the elements, with special attention tovalency(that is, the number of single bonds the element can form), Mendeleev proposed the periodic law, by which “the elements arranged according to the ...
