The alkaline earth metals representthe second columnon the periodic table. Its six elements extend from beryllium (Be) to radium (Ra). These metals are named for forming basic solutions when put into water. They tend to form cations with a positive two charge and bond ionically. What are l...

have symbols based on their Latin names, for example: 另外有些早已为人所知的元素的符号是拉丁文名字的缩写(是建立在拉丁文名字的基础上的) ,例如: Iron(英文名字)=Fe(缩写)(ferrum) (拉丁文名字) copper=Cu(cuprum) lead=Pb(plumbum) A complete listing of the elements may be found in Table 1. ...
A table with common ionic charges can also help determine oxidation states and chemical reactions. For example, knowing that iron can have a +2 or +3 charge can help predict the formation of compounds like FeO (iron(II) oxide) or Fe2O3(iron(III) oxide). Based on the common charges,...

1. The Elements and The Periodic Table元素和周期表The number of protons in the nucleus of an atom is referred to as the atomic
The periodic table contains an enormous amount of information, but some of the most important are atomic numbers, atomic symbols, and atomic masses. Atomic number:The number of protons in an atom's nucleus is referred to as the atomic number of that element. The number of protons defines wha...
The reactivity of the alkali metals increase going down the group; however, the reactivities of the halogens decrease going down the group. Why do the reactivities of these two groups differ? Based on position in the periodic table and electron configur...
Notice the use of noble-gas symbols to simplify the electron-configuration notation. Recommended video on the shell model of the atom: Valence electrons and the periodic table (TylerDewit, 17 min) In particular, the number of outer-shell electrons (which is given by the rightmost digit in ...
