1) How many half-filled orbitals do each of the following have in the ground state?
a) O
b) B
c) Ar
d) Mn
e) K
f) Cf
g) Zn
MULTIPLE CHOICE::::
1) Carbon absorbs energy at a wavelength of 150 nm. The total amount of energy emitted by a carbon sample is 1.98 x 10^5 J. Calculate the number of carbon atoms present in the sample, assuming that each atom emits one photon.
a) 1.50 x 10^23
b) 2.50 x 10^19
c) 1.48 x 10^20
d) 1.65 x 10^5
2) Calculate the wavelength of a photon traveling at a velocity of 0.01 c (speed of light). c=3.0 x 10^8 m/s.
a) 3.4 x 10^-55 m
b) 1.3 x 10 ^/15 m
c) 1.9 x 10^-28 m
d) 1.9 x 10^-28
(yes, c and d are the same in my packet)
