The electronic configuration of an atom describes the distribution of electrons in different energy levels or orbitals around the nucleus. These electrons fill orbitals starting from the lowest energy level to higher ones according to the Aufbau principle.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>1. Aluminum (Al):<\/strong><br>Aluminum has 13 electrons in its neutral state. These electrons are arranged as follows:<br>Two electrons fill the first energy level (1s\u00b2), eight electrons fill the second energy level (2s\u00b2 2p\u2076), and the remaining three fill the third energy level (3s\u00b2 3p\u00b9). This gives the full configuration of 1s\u00b2 2s\u00b2 2p\u2076 3s\u00b2 3p\u00b9.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">When aluminum loses three electrons to form Al\u00b3\u207a, it loses them from the outermost energy level (the third shell). This results in a stable configuration identical to that of neon, a noble gas. So the Al\u00b3\u207a ion has the configuration 1s\u00b2 2s\u00b2 2p\u2076.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>2. Oxygen (O):<\/strong><br>Oxygen has 8 electrons in its neutral state. Its configuration is:<br>Two electrons go into the 1s orbital, two into the 2s, and four into the 2p orbitals, giving 1s\u00b2 2s\u00b2 2p\u2074.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Oxygen tends to gain two electrons to achieve a full outer shell like neon. When it gains two electrons, it becomes the O\u00b2\u207b ion, and its configuration becomes 1s\u00b2 2s\u00b2 2p\u2076. This configuration shows a stable, full outer shell, which makes the ion more stable than the neutral atom.<\/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-banner8-966.jpeg\" alt=\"\" class=\"wp-image-37756\" srcset=\"https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-966.jpeg 852w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-966-250x300.jpeg 250w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-966-768x923.jpeg 768w\" sizes=\"auto, (max-width: 852px) 100vw, 852px\" \/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Give the electronic configuration of 1.
