Question:
Using spdf and noble gas notations, write electron configurations for atoms of the following elements. (Try to do this by looking at the periodic table but not at Table 7.3.)
(a) Strontium, Sr. This element is named for a town in Scotland.
(b) Zirconium, Zr. The metal is exceptionally resistant to corrosion and so has important industrial applications. Moon rocks show a surprisingly high zirconium content compared with rocks on Earth.
(c) Rhodium, Rh. This metal is used in jewelry and in catalysts in industry.
(d) Tin, Sn. The metal was used in the ancient world. Alloys of tin (solder, bronze, and pewter) are important.
Data Given in Table 7.3
