[Ar]3d\u00b9\u2070<\/strong><\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<p><strong>Explanation:<\/strong><\/p>\n\n\n\n<p>Zinc (Zn) has an atomic number of 30, which means a neutral zinc atom has 30 electrons. The electron configuration of a neutral Zn atom is:<\/p>\n\n\n\n<p><strong>Zn: 1s\u00b2 2s\u00b2 2p\u2076 3s\u00b2 3p\u2076 4s\u00b2 3d\u00b9\u2070<\/strong><br>In abbreviated form, this is written as:<br><strong>[Ar] 4s\u00b2 3d\u00b9\u2070<\/strong><\/p>\n\n\n\n<p>When zinc becomes a <strong>Zn\u00b2\u207a ion<\/strong>, it loses <strong>two electrons<\/strong>. Electrons are always lost from the outermost energy level first, which is the <strong>4s orbital<\/strong> in this case\u2014not the 3d orbital, even though the 3d sublevel is written after 4s. So we remove both electrons from the 4s orbital:<\/p>\n\n\n\n<p><strong>Zn\u00b2\u207a: [Ar] 3d\u00b9\u2070<\/strong><\/p>\n\n\n\n<p>This gives us a full 3d subshell and no 4s electrons. The 3d orbitals are now completely filled, giving zinc ion a <strong>stable and symmetrical electron configuration<\/strong>.<\/p>\n\n\n\n<p>Now let\u2019s examine the answer choices:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>a. [Ar]4s\u00b23d\u2078<\/strong> \u2013 Incorrect; this has two 4s electrons and only 8 in the 3d subshell, which does not match the Zn\u00b2\u207a configuration.<\/li>\n\n\n\n<li><strong>b. [Ar]3d\u00b9\u2070<\/strong> \u2013 <strong>Correct<\/strong>; this matches the expected configuration of Zn\u00b2\u207a after losing two 4s electrons.<\/li>\n\n\n\n<li><strong>c. [Ar]4s\u00b23d\u00b9\u2070<\/strong> \u2013 Incorrect; this is the configuration of neutral Zn, not Zn\u00b2\u207a.<\/li>\n\n\n\n<li><strong>d. [Ar]3d\u00b9\u20704s\u00b2<\/strong> \u2013 Incorrect; same as (c), just with a reversed order that still represents neutral Zn.<\/li>\n<\/ul>\n\n\n\n<p>Therefore, the <strong>correct abbreviated electron configuration for the zinc ion Zn\u00b2\u207a is [Ar]3d\u00b9\u2070<\/strong><\/p>\n\n\n\n<p><\/p>\n\n\n\n<p>.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"1024\" src=\"https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner5-106.jpeg\" alt=\"\" class=\"wp-image-28156\" srcset=\"https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner5-106.jpeg 1024w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner5-106-300x300.jpeg 300w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner5-106-150x150.jpeg 150w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner5-106-768x768.jpeg 768w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Identify the correct abbreviated electron configuration for the zinc ion: Group of answer choices a.
