( a ) What is the full and abbreviated electron configuration for this element ? Explain how you arrived at this configuration . In other words , don ' t just give me the configuration , but walk me through and explain to me how exactly you arrived at your answer .
( b ) In this Lesson we talked about the relationship between frequency and wavelength . The relationship can actually be expressed as
where f is the frequency , c is the speed of light ( see below ), and lambda ( the symbol on the left of the equals sign that looks like an upside down y ) is wavelength . The particle nature of light was first proposed by Einstein , who suggested that light could be described as a stream of particles called photons . A photon of a certain wavelength ( lambda) has an energy ( E) given by the equation :
where E is the energy of the photon in J , h is Planck ' s constant ( 6.626 x 10 -34 J * s ), and c is the
speed of light ( 3.00 x 10 8 m / s ). If we determine the wavelength ( lambda) of light emitted from a sample of antimony to be 206.8 nm , what is the energy ( E ) and frequency ( f ) that corresponds to this wavelength ?
12 . Think about it--why is the line spectrum produced by excited barium atoms more complex than the line spectrum produced by excited sodium atoms ? Be sure to base your answer on what we discussed in THIS class and use the terminology from the materials in THIS course . Your answer must be sufficiently detailed to receive credit
