Each element has a unique configuration based on its atomic number, which tells us how many electrons are present in a neutral atom. For Strontium (Sr), the atomic number is 38, meaning it has 38 electrons.<\/p>\n\n\n\n<p>To write the <strong>full electron configuration<\/strong>, we begin filling the orbitals from the lowest energy level to the highest. The order follows the Aufbau principle:<br>1s \u2192 2s \u2192 2p \u2192 3s \u2192 3p \u2192 4s \u2192 3d \u2192 4p \u2192 5s \u2192 4d \u2192 5p \u2192 6s.<\/p>\n\n\n\n<p>Applying this to Strontium:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The first 2 electrons go into 1s (1s\u00b2),<\/li>\n\n\n\n<li>The next 2 into 2s (2s\u00b2),<\/li>\n\n\n\n<li>Then 6 into 2p (2p\u2076),<\/li>\n\n\n\n<li>Followed by 2 into 3s (3s\u00b2),<\/li>\n\n\n\n<li>6 into 3p (3p\u2076),<\/li>\n\n\n\n<li>2 into 4s (4s\u00b2),<\/li>\n\n\n\n<li>10 into 3d (3d\u00b9\u2070),<\/li>\n\n\n\n<li>6 into 4p (4p\u2076),<\/li>\n\n\n\n<li>2 into 5s (5s\u00b2),<\/li>\n\n\n\n<li>10 into 4d (4d\u00b9\u2070),<\/li>\n\n\n\n<li>6 into 5p (5p\u2076),<\/li>\n\n\n\n<li>And the last 2 into 6s (6s\u00b2).<\/li>\n<\/ul>\n\n\n\n<p>For the <strong>shorthand configuration<\/strong>, we use the noble gas that comes before the element. Krypton (Kr) has 36 electrons, so we write [Kr] to represent all those. After that, we add the electrons unique to Strontium: two more in the 5s orbital.<\/p>\n\n\n\n<p>Therefore, the shorthand electron configuration for Strontium is:<br><strong>[Kr] 5s\u00b2<\/strong><\/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-banner8-803.jpeg\" alt=\"\" class=\"wp-image-36586\" srcset=\"https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-803.jpeg 852w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-803-250x300.jpeg 250w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-803-768x923.jpeg 768w\" sizes=\"auto, (max-width: 852px) 100vw, 852px\" \/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Using carbon (shown below) as an example for how to write out the electron configuration for an element: a.
