Question 11 of 12
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 (noble gas notation) 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) How many total electrons does antimony have? Are there any other neutral elements that have this number of total electrons? How many valence electrons does antimony have? Are there any other neutral elements that have this number of valence electrons?
Question 12 of 12
5.0 Points
(a) Discuss the difference in the shapes of s and p orbitals. (b) How many electrons does each orbital hold? (c) Which of these orbitals do electrons occupy first? (d) Which of these orbitals has the electrons with the highest energy, assuming both orbitals are in the same energy level? 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, and properly labeled according to the letters above.
