On December 5, 1971, at the mere age of 35, the great composer Wolfgang Amadeus Mozart died after a three month long battle with illness. Rumor was that a rival musician had poisoned him, but it turned out that common consensus was that the antimony prescription that doctors had prescribed him was actually poisoning him.(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 108 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?

If a person were to guess a number from 1-10, the chance of guessing a 4 would be 0.1. If 5 people were asked to guess a number from 1-10, the chance of guessing a 4 would be 0.5. The chance of 2 people guessing a 4 would be (0.1)(01.)=(0.01), correc..
