标题[问题] 三个小问题
时间Fri Jun 25 00:23:12 2010
1.请问填路易式点的时候，是要用类似罕德定则的方式填吗??
ex.Si 是每边都一颗，还是可以填一边两颗，其余两边各一颗??
2.What would be the best description of Einstein's explantion of the
photoelectric effect?
a.electrons have a definite mass
b.ejection of photons occurs when the intensity of light increases beyond
a certain minimun
c.light consists of "particles" with a definite mass
d.light consists of "particles" with a definite energy
e.ejection of photons occurs when the energy of the photon is greater than
a certain minimun
我是选d，有人可以解释一下吗?
3.PCl5 is molecule with a trigonal bipyramidal geometry. There are two types
of bond lenths in this structure: axial and equatorial. Predict which one
is longer?
我是觉得在axial上的键长会比较长，因为它的斥力会比equatorial来的小
不是很确定...有请好心人解说 谢谢!!

1F：推 cen71:1的填法我看讲义都是一颗一颗点 只有He是两颗在同边 06/25 00:40
2F：→ cen71:2爱因斯坦是主张 光可视为不连续的小能块 也就是波粒二像性 06/25 00:42
3F：推 cen71:我也觉得是d~ ~ 06/25 00:45
4F：→ cen71:3 轴键与赤道键的差别在於轨域的S% 因为轴上S%较高 所以键能 06/25 00:47
5F：→ cen71: 这边是赤道 06/25 00:48
6F：→ cen71:赤道键较强 键长较短 06/25 00:48
