(full score 60)
1. Give three experimental results by the end of 19th century that cannot be
explained by the classical mechanics. (10)
2. For the A4 family, CO2 gas is a prevailing species on the earth, however,
SiO2 gas is rarely observed. Explain. (5).
3. At 0 K, should the molecule be frozen? If not, explain your answer (3).
Can you link this question with Heisenberg's uncertainty principle? (2)
4. Supposed that the electron is moving around a circle with a diameter 2r
(the potential energy = 0) and the motion is wavelike.
Applying de Broglie relationship and standing wave to prove that
the associated energy of the motion has to be quantized. (10)
5. In a one dimensional motion, the kinetic energy operator can be expressed
as:http://ppt.cc/DozN
Accordingly, show momentum p in terms of operator (10)
6. Could electron in 1s orbital be excited by light (in other words, absorb
the photon) and then jump to 2s orbital? Explain (10)
7. Write down the full name of VSEPR (5). What is the formal charge of CO
(C and O)? (5)
