To construct it, we begin by calculating the <strong>total number of valence electrons<\/strong>. Tin contributes 4, and each of the six fluorine atoms contributes 7, resulting in 46 electrons. Since the ion carries a 2\u207b charge, we add 2 more, giving us <strong>48 valence electrons<\/strong> in total.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Next, we identify the central atom. Tin (Sn) is less electronegative than fluorine and has the ability to expand its valence shell due to its position in Period 5. Thus, it becomes the central atom with six fluorine atoms arranged symmetrically around it.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">We then <strong>form single bonds<\/strong> between Sn and each F. These 6 single bonds consume 12 electrons. The remaining <strong>36 electrons<\/strong> are used to complete the octets of the surrounding fluorine atoms by placing three lone pairs (6 electrons) on each.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">After placing all 48 electrons, we check the octets. Each fluorine has 8 electrons: 6 from lone pairs and 2 from the Sn\u2013F bond. Tin forms 6 bonds, and while it exceeds the octet, this is acceptable for elements in Period 5 or beyond due to available d orbitals.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Finally, we enclose the structure in brackets to denote it is an ion and indicate the <strong>2\u207b charge<\/strong> in the upper right corner. This complete Lewis structure helps us understand the molecule\u2019s bonding, electron distribution, and overall charge, which is important for predicting reactivity and molecular geometry.<\/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-banner5-82.jpeg\" alt=\"\" class=\"wp-image-27990\" srcset=\"https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner5-82.jpeg 1024w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner5-82-300x300.jpeg 300w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner5-82-150x150.jpeg 150w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner5-82-768x768.jpeg 768w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Draw the Lewis structure for the SnF62- ion.
