1.請問填路易式點的時候，是要用類似罕德定則的方式填嗎??
ex.Si 是每邊都一顆，還是可以填一邊兩顆，其餘兩邊各一顆??
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
我是選d，有人可以解釋一下嗎?
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?
我是覺得在axial上的鍵長會比較長，因為它的斥力會比equatorial來的小
不是很確定...有請好心人解說 謝謝!!

1F：推 cen71:1的填法我看講義都是一顆一顆點 只有He是兩顆在同邊 06/25 00:40
2F：→ cen71:2愛因斯坦是主張 光可視為不連續的小能塊 也就是波粒二像性 06/25 00:42
3F：推 cen71:我也覺得是d~ ~ 06/25 00:45
4F：→ cen71:3 軸鍵與赤道鍵的差別在於軌域的S% 因為軸上S%較高 所以鍵能 06/25 00:47
5F：→ cen71: 這邊是赤道 06/25 00:48
6F：→ cen71:赤道鍵較強 鍵長較短 06/25 00:48
