我们使用electronic configuration的目的就在于,我们可以快速判断电子的分布情况。 我们也可以根据最外层电子数,最快锁定一个原子是否丢失或者获得某些电子,成为离子。 对于电子数比较多的,还有一种简便的写法(condensed configuration),先把前面最靠近你正在写electronic configuration的原子的noble gas写出来,再写出剩下的。
1.Name the noble gas atom that has the same electron configuration as each of the ions in the following compounds.a.aluminum sulfide, Al2S3b.magnesium nitride , Mg3N2c.rubidium oxide. CsI2.Foe each of the following pairs , indicate which species is larger.Explain your reasoning in the ...
Another way of expressing this and other electron configurations is to use the symbol for the noble gas preceding the element in question, which assumes its electron configuration, and add on the additional orbitals. So sulfur, our example above, can be written [Ne] 3s23p4. Orbital Notation ...
noble gas atoms (He, Ne, Ar, Kr, Xe) were determined respectively in the energy range from 150 through 4000 and from 2400 through 4000 eV. This was done by shooting a well confined K + or Cl - beam through a collision chamber filled with the target gas. From these cross section ...
