Ions with all electrons paired exhibit <strong>diamagnetism<\/strong>, meaning they are weakly repelled by magnetic fields. In contrast, ions with one or more unpaired electrons exhibit <strong>paramagnetism<\/strong>, meaning they are attracted by magnetic fields due to their net magnetic moment.<\/p>\n\n\n\n<p><strong>Cd\u207a<\/strong>, having lost only one electron, retains the [Kr] 4d\u00b9\u2070 5s\u00b9 configuration. The single 5s electron remains unpaired, making Cd\u207a paramagnetic.<\/p>\n\n\n\n<p><strong>Au\u207a<\/strong> is unusual. Neutral gold has a filled 5d shell and one 6s electron. Upon losing the 6s\u00b9 electron to become Au\u207a, the resulting 5d\u00b9\u2070 is fully filled. No unpaired electrons remain, hence Au\u207a is diamagnetic.<\/p>\n\n\n\n<p><strong>Mo\u00b3\u207a<\/strong> arises when Mo loses its two 5s and one 4d electron. The resulting 4d\u00b3 configuration includes three unpaired electrons, firmly qualifying Mo\u00b3\u207a as paramagnetic.<\/p>\n\n\n\n<p><strong>Zr\u207a<\/strong> loses one electron, typically from the 5s orbital first, resulting in 4d\u00b2 5s\u00b9. Both 4d and 5s orbitals contain unpaired electrons. Zr\u207a thus has three unpaired electrons, making it paramagnetic.<\/p>\n\n\n\n<p>This analysis underscores the importance of electron configuration in predicting chemical and physical behavior, particularly for ions of transition metals. Understanding how orbital occupancy changes with ionization is vital to determining an ion&#8217;s magnetic character.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"722\" height=\"1024\" src=\"https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner10-170.jpeg\" alt=\"\" class=\"wp-image-29926\" srcset=\"https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner10-170.jpeg 722w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner10-170-212x300.jpeg 212w\" sizes=\"auto, (max-width: 722px) 100vw, 722px\" \/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>&#8216;Write the full electron configuration and orbital diagram for each ion and indicate whether it is diamagnetic or paramagnetic (10 pts): Cdl+ b.
