英文的化学题,= =,
1.Name the noble gas atom that has the same electron configuration as each of the ions in the following compounds.
a.aluminum sulfide,Al2S3
b.magnesium nitride ,Mg3N2
c.rubidium oxide.CsI
2.Foe each of the following pairs ,indicate which species is larger.Explain your reasoning in the terms of the electron structure of each species.
a.Li+ or F-
b.Na+ or Cl-
c.Ca2+ or Ca
d.Cs+ or I-

答

1、C 是错的。
C指的是铷的氧化物，应该是Rb2O
2、
A、F-更大。F-有2层，而Li+就只有1层
B、Cl-更大，Cl-有3层，而Na+就只有2层
C、Ca失去2个电子变成Ca2+,所以，Ca更大。
D、Cs+ 核外电子结构结构与I- 一样，根据核电荷数越大，半径越小，所以，I- 更大。

答

1、问题意思是找出构成物质的两种原子具有相同的电子构型的稀有气体元素名称.
a 与Al3+和S2-电子构型相同的稀有气体分别是Ne和Ar
b Mg2+和N3-电子构型相同,2 8结构,相应的稀有气体元素都为Ne
c Cs+和I-电子构型相同,2 8 18 18 8结构,相应的稀有气体元素都为Xe
2、
a F-大,有2个电子层,Li+只有一个电子层
b Cl-大,Cl-有3个电子层,Na+只有2个电子层
c Ca大,Ca有4个电子层,Ca2+只有3个电子层
d I-大,虽然它们电子构型相同（核外电子数相同）,但I-的质子数比Cs+少,对核外电子吸引力弱一些,所以半径大一些
