When forming cations, the electrons are removed in the order of orbital energies, which places s-orbitals above d-orbitals in atomic configuration despite their opposite order during filling. This pattern governs the configurations for each ion.<\/p>\n\n\n\n<p><strong>Manganese (Mn\u00b2\u207a)<\/strong> begins as [Ar]4s\u00b23d\u2075. Losing two electrons from 4s leaves [Ar]3d\u2075, which is a half-filled, stable arrangement.<\/p>\n\n\n\n<p><strong>Hafnium (Hf\u00b2\u207a)<\/strong> has the neutral configuration [Xe]6s\u00b24f\u00b9\u20745d\u00b2. It loses both 6s electrons, yielding [Xe]4f\u00b9\u20745d\u00b2, a common oxidation state for Hf.<\/p>\n\n\n\n<p><strong>Cobalt (Co\u00b3\u207a)<\/strong> starts from [Ar]4s\u00b23d\u2077. Removing two 4s and one 3d electron results in [Ar]3d\u2076.<\/p>\n\n\n\n<p><strong>Iron (Fe\u00b3\u207a)<\/strong> is initially [Ar]4s\u00b23d\u2076. After losing two 4s and one 3d electron, it becomes [Ar]3d\u2075, which is especially stable due to half-filled d-orbitals.<\/p>\n\n\n\n<p><strong>Silver (Ag\u207a)<\/strong> has the neutral form [Kr]5s\u00b94d\u00b9\u2070. It loses the 5s electron, resulting in the filled-shell configuration [Kr]4d\u00b9\u2070.<\/p>\n\n\n\n<p><strong>Molybdenum (Mo\u00b3\u207a)<\/strong> in the ground state is [Kr]5s\u00b94d\u2075. Upon removing the 5s\u00b9 and two 4d electrons, it stabilizes at [Kr]4d\u00b3.<\/p>\n\n\n\n<p>Recognizing these patterns helps to predict reactivity, bonding, and magnetic behavior of transition metals in coordination chemistry and catalysis.<\/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-banner10-169.jpeg\" alt=\"\" class=\"wp-image-29922\" srcset=\"https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner10-169.jpeg 722w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner10-169-212x300.jpeg 212w\" sizes=\"auto, (max-width: 722px) 100vw, 722px\" \/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Match each transition metal ion with its condensed ground-state electron configuration.
