The periodic table is a tabular display of the chemical elements, organized on the basis of their properties. Elements are presented in increasing atomic number. The main body of the table is a 18 7 grid, with gaps included in to keep elements with similar properties together, such as the halogens and the noble gases. These gaps form four distinct rectangular areas or blocks. The f-block is not included in the main table, but rather is usually floated below, as an inline f-block would make the table impractically wide. The periodic table accurately predicts the properties of various elements and the relations between properties. As a result, it provides a useful framework for analyzing chemical behavior, and is widely used in chemistry and other sciences. 请您评价及分享这个应用程序,因为它是免费的:-) 像我们在Facebook:https://www.facebook.com/whitesofinfo在Twitter关注我们:https://www.twitter.com/whitesof寻找我们的应用程序在:http://www.whitesof.com/apps 在英国,美国,印度,新加坡,中国香港,韩国,澳大利亚和巴西排在第1的应用程序,它的快速参考。 元素周期表是化学元素,有组织它们的属性的基础上,以表格形式显示。元素都在不断增加原子序数。在表的主体是一个187网格,与包括在保持具有类似性质的元素的合计,如卤素和稀有气体的间隙。这些差距形成四个不同的矩形区域或块。 f区不包括在主台,而是在下面通常被浮动,作为内嵌f区会使表不切实际宽。周期表中准确地预测各种元素和属性之间的关系的性质。其结果是,它提供了用于分析化学行为的有用框架,并且被广泛用于化学和其他科学。 更多
