78.1. THE PERIODIC TABLE 元素周期表 (图片可点击放大) In this section, we will explore the periodic table, which organizes chemical elements and provides valuable information about their properties and relationships. Understanding the periodic...
More so than any of the other major groups of elements in the periodic table, the transition metals have shaped human history and have been the workhorses of industry. The discovery of metallic copper ended the Stone Age and ushered...

Using the periodic table, identify the heaviest member of each of the following groups: alkali metals chalcogens noble gases alkaline earth metals Use the periodic table to give the name and symbol for each of the following elements: the noble gas in the same period as germanium ...
Noble gases: He, Ne, Ar, Kr, Xe, Rn, and Og. Names not recognised by IUPAC but in common use are: Platinum group metals: Ru, Rh, Pd, Os, Ir, and Pt; Coinage metals: Cu, Ag, and Au. Images of various periodic tables
was there an accurate or reliable model of atoms that could describe observed chemical behaviors. The so-called 'noble gases' (helium, neon, xenon, etc.) and many other elements were unknown. As more elements were identified, however, Mendeleev's crude periodic table was expanded and refined....
