Question

True or false:

a. n(initial) and n(final) are integers.

b. n(initial) is less that n(final)

c. long wavelength emissions have lower energy compared to short wavelength emissions.

d. if the electromagnetic wavelength is known, the energy can be calculated according to the formula hc/wavelength

e. to test hypothesis that n(final)=1, n(initial) must start at 3

f. to test hypothesis that n(final)=1, plot 1/wavelngth versus n(initial)^2

g. the hydrogen atom ionization energy can be determined from consideration of the emission spectrum of the hydrogen atom

h. the highest electronic energy in the hydrogen atom is 0 J

I. the lowest electronic energy in the hydrogen atom is 2.18*10^-18 J

Explanation / Answer

a)

true, since n = 1,2,3... rules from aufbau principles, i.e. levels must be positiv eintegers

b)

n initial typically is larger than nfinal, since there is a drop in level

c.

long WL --> low Energy

short WL --> high energy, due to

E = hc/WL, where h and c are constant, then ther eis inverse proportion

d.

IF you do not know wavelength, the use, E = hv, which uses frequency, so this is false
