The figure above shows different possible transitions of electrons as they move from higher energy states to lower energy states. Which transition will produce the spectrum line with the shortest wavelength in this element’s atomic spectrum?
A
B
C
D
A chemistry graduate student is very skilled at analyzing atomic emission spectra. The print out of her spectrum is printed in black and white. Therefore she has to rely on comparing the widths and positions of spectral lines during analysis. Observe the various atomic emission spectra.
Which of the elements shown make up the unknown spectra?
Hydrogen
Helium
Sodium
Copper
Strontium
All of the elements
Each arrow shows an electron moving from one energy level to another. Which transitions will release energy?
A and D
B and C
only A
only C
What happens when an electron in a Bohr atom moves to a higher energy level?
It absorbs energy
It creates a new element
It becomes a proton
It loses energy
In the Bohr Model, which part of the atom is found in the nucleus?
Neutrons only
Electrons
Protons only
Protons and neutrons
