Sulfur, being more electronegative, holds 2 lone pairs to complete its octet. Silicon, with fewer valence electrons, holds 1 lone pair. Together, these account for 3 lone pairs, and all 10 valence electrons are properly assigned. This structure satisfies the octet rule for sulfur and gives a stable configuration for both atoms<\/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-banner8-121.jpeg\" alt=\"\" class=\"wp-image-26849\" srcset=\"https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-121.jpeg 852w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-121-250x300.jpeg 250w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-121-768x923.jpeg 768w\" sizes=\"auto, (max-width: 852px) 100vw, 852px\" \/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>How many lone pairs in the lewis dot structure of SiS2 The Correct Answer and Explanation is: To determine how many lone pairs are in the Lewis dot structure of SiS (silicon monosulfide), we first need to follow proper steps for drawing the structure.
