試題 :
1.Who is the first " Chemist " to introduce the quantitative measurement to
Science? (10 pts)
2.What is the basic assumption of Avogadro's hypothesis: at the same
temperature and pressure, equal volumes of different gases contain the same
number of particles. What is the formula of the gaseous product when a
reaction of 1 L of chlorine gas (Cl2) with 3 L of fluorine gas (F2) yields
2 L of a gaseous product? (20 pts)
3.In 1885, Balmer first detected the atomic spectrum of H-atom. He found that
Only certain energies characterized by the wavelength at 410 nm, 434 nm,
486 nm, and 656 nm are emitted by excited H-atom. Calculate the wavelength
of light emitted from (a) n=2 to n=1, (b) n=3 to n=2 and (c) n=4 to n=3
in the hydrogen (H) atom. Please indicate which transition was detected
by Balmer.(30 pts)

4.Derive the de Broglie equation from the Eienstein equation , E=mc and Plank
equation E = nhυ. Calculate the de Bronglie wavelength for a ball (0.14kg)
-31 7
traveling at 40 m/s and an electron (9.11*10 kg) traveling at 1.0*10 m/s.
What experimental evidence was conducted to support de Broglie equation?
What do you learn from these calculations? (40 pts)
5.Which of the following orbital designations are incorrect: 1s, 1p, 2p, 2d,
3p, 3f, 4d, 4f, 8p, 9d. Please indicate how many orbitals can be found when
n=2 and 4. (20 pts)
6.Please list three major results from solving the problem of " a particle in
a box " by using Schrodinger wave equation: HΨ = EΨ. (20%)
