(True or False) Bohr's model was a great accomplishment and provided an accurate view of the emission spectra of many atoms.

False

(True or False) Each element has an identical line spectrum.

False

(True or False) In their lowest energy state, atoms are known to contain up to only four energy levels.

False

Essay (HONORS CHEMISTRY ONLY) What did Bohr's model help to explain? Why did scientists feel the need to replace it with a new model?

Look @ page 95-96

(True or False) According to the Bohr model, the frequency of the spectral lines in the hydrogen atom can be predicted by the presence of colored lines in an emission spectrum.

True

(True or False) Using spectroscopy, Bohr devised a model describing the movements of electrons around a nucleus.

True

(Multiple Choice) Niels Bohr proposed the concept of principal energy levels, which he envisioned as a set of circular tracks on which (BLANK) orbited.

electrons

(Multiple Choice) Which of the following accurately describes the Bohr model?

electrons exist in a series of distinct energy levels

(Multiple Choice) What is the pattern for colored lines that was discovered while analyzing light produced by heated elements?

emission spectrum

(Multiple Choice) Bohr's model accurately illustrated the emission spectra of a(n) (BLANK) atom.
