Textbook Question
Chapter 7, Problem 8PS
The lanthanides, once called the rare earth elements, are really only “medium rare” Using noble gas and spdf notations, depict reasonable electron configurations for the following elements.
(a) Samarium, Sm. This lanthanide is used in magnetic materials.
(b) Ytterbium, Yb. This element was named for the village of Ytterby in Sweden, where a mineral source of the element was found.

Some important notes:
• Draw the major product, or products, of this reaction in the drawing area below.
• You can draw the products in any arrangement you like.
• Pay careful attention to the reaction conditions, and only include the major products.
• Be sure to use wedge and dash bonds when necessary, for example to distinguish between major products that are enantiomers.
• Note that there is only 1 equivalent of HBr reactant, so you need not consider the case of multiple additions.
