Question:

Neodymium is a component of powerful magnets.
(a) Neodymium has three common oxidation states: +2, +3, and +4. Give the electron configurations for Nd and its three positive oxidation states.
(b) Are any of the common Nd ions paramagnetic?
(c) Neodymium magnets, which are composed of Nd, Fe, and B, were developed because samarium-based magnets (SmCo) were very costly. What is the empirical formula for the neodymium-based magnet material if it is 26.68% Nd, 72.32% Fe, and the remainder B?Neodymium magnets Cengage Learning/Charles D. Winters
