BOHR MODEL (ENERGY LEVELS) Flashcards
1
Q
emission spectra:
A
when electricity is passed through a tube containing a single gas, a “discrete emission spectrum” is observed
2
Q
discrete emission spectrum:
A
has discrete spectral lines seen on the spectrum of isolated atoms of a chemical element, which only absorbs and emits light at particular wavelengths
3
Q
Who discovered the Bohr Model?
A
“Niels Bohr (1913) proposed a change to the Planetary Model to explain the emission lines
4
Q
valence level:
A
the outermost principle energy level, which is the level furthest away from the nucleus that still contains electrons
5
Q
valence electrons:
A
they determine the chemical properties of an atom
