For <strong>thallium (Tl)<\/strong>, with atomic number 81, the abbreviated electron configuration uses the previous noble gas xenon (Xe) as a core to simplify the notation. After xenon, electrons fill the 4f, 5d, 6s, and 6p orbitals. The valence electrons in thallium are in the 6s\u00b2 and 6p\u00b9 orbitals because they are the highest principal energy level, making a total of <strong>3 valence electrons<\/strong>.<\/p>\n\n\n\n<p>For <strong>polonium (Po)<\/strong>, which has 84 electrons, the valence electrons are those in the outermost energy level, specifically 6s\u00b2 and 6p\u2074. This gives polonium a total of <strong>6 valence electrons<\/strong>, typical of elements in Group 16 (the oxygen family), which tend to form \u22122 anions due to their high electron affinity.<\/p>\n\n\n\n<p>The <strong>3d sublevel<\/strong> belongs to the third principal energy level and includes five orbitals. Each orbital can hold two electrons, giving the d sublevel a capacity of 10 electrons, but the number of orbitals remains 5. These five orbitals are labeled as 3d\u2093\u1d67, 3d\u1d67\ud835\udccf, 3d\ud835\udccf\u00b2, 3d\u2093\ud835\udccf, and 3d\u2093\u00b2\u2013\u1d67\u00b2.<\/p>\n\n\n\n<p>For <strong>Mg\u00b2\u207a<\/strong>, the electron configuration begins with 1s\u00b2 and continues through the 3s orbital. However, since the magnesium ion loses two electrons to form a +2 charge, these are removed from the outermost 3s orbital, leaving the configuration as <strong>1s\u00b2 2s\u00b2 2p\u2076<\/strong>. There are no valence electrons left in the third shell, so the ion has <strong>no valence electrons<\/strong>, which makes it very stable and unreactive in this form.<\/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-banner5-97.jpeg\" alt=\"\" class=\"wp-image-28098\" srcset=\"https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner5-97.jpeg 1024w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner5-97-300x300.jpeg 300w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner5-97-150x150.jpeg 150w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner5-97-768x768.jpeg 768w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Write the abbreviated electron configuration for thallium.
