The symbol <strong>XeXeXe<\/strong> is a shorthand that represents the electron configuration of <strong>xenon<\/strong>, a noble gas with an atomic number of <strong>54<\/strong>. So, the configuration already accounts for the first 54 electrons.<\/p>\n\n\n\n<p>Now we look at the remaining electrons beyond xenon:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>6s\u00b2<\/strong> adds 2 electrons<\/li>\n\n\n\n<li><strong>4f\u00b9\u2074<\/strong> adds 14 electrons<\/li>\n\n\n\n<li><strong>5d\u00b9\u2070<\/strong> adds 10 electrons<\/li>\n\n\n\n<li><strong>6p\u00b2<\/strong> adds 2 electrons<\/li>\n<\/ul>\n\n\n\n<p>Add these to xenon&#8217;s 54 electrons:<\/p>\n\n\n\n<p>54 (from Xe) + 2 (6s\u00b2) + 14 (4f\u00b9\u2074) + 10 (5d\u00b9\u2070) + 2 (6p\u00b2) = <strong>82 electrons<\/strong><\/p>\n\n\n\n<p>The atomic number of an element is equal to the number of protons, which is also the number of electrons in a neutral atom. Therefore, this atom has <strong>82 electrons<\/strong>, meaning its atomic number is <strong>82<\/strong>.<\/p>\n\n\n\n<p>Looking at the periodic table, the element with atomic number <strong>82<\/strong> is <strong>lead<\/strong>, and its symbol is <strong>Pb<\/strong>.<\/p>\n\n\n\n<p>Lead is in period 6 and group 14 (IVA), which matches the valence configuration <strong>6s\u00b2 6p\u00b2<\/strong>, characteristic of group 14 elements. The presence of filled <strong>4f<\/strong> and <strong>5d<\/strong> subshells is also typical for heavier elements in period 6.<\/p>\n\n\n\n<p>This configuration shows that lead is a <strong>post-transition metal<\/strong>, and it is the heaviest stable element found in nature. It has applications in batteries, shielding against radiation, and historically in pipes and paints.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"852\" height=\"1024\" src=\"https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-1076.jpeg\" alt=\"\" class=\"wp-image-38869\" srcset=\"https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-1076.jpeg 852w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-1076-250x300.jpeg 250w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-1076-768x923.jpeg 768w\" sizes=\"auto, (max-width: 852px) 100vw, 852px\" \/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Determine the identity of the element with the following electron configuration.
