Here&#8217;s an explanation:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Lewis Structure of SiH\u2084:<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Silicon (Si) is the central atom, as it is less electronegative than hydrogen (H).<\/li>\n\n\n\n<li>Silicon is in Group 14 (4A) of the periodic table, which means it has 4 valence electrons.<\/li>\n\n\n\n<li>Hydrogen, being in Group 1 (1A), has 1 valence electron and needs only 1 more electron to complete its duet (2-electron shell).<\/li>\n<\/ul>\n\n\n\n<p>To draw the Lewis structure:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Place Si in the center<\/strong>, with four hydrogens (H) around it.<\/li>\n\n\n\n<li>Each hydrogen forms a <strong>single bond<\/strong> (a shared pair of electrons) with silicon. Since silicon has 4 valence electrons, it shares one electron with each hydrogen atom, forming <strong>four Si\u2013H bonds<\/strong>.<\/li>\n<\/ol>\n\n\n\n<h3 class=\"wp-block-heading\">Electron Distribution:<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Silicon shares its 4 valence electrons with the 4 hydrogens. This gives silicon a total of 8 electrons (satisfying the octet rule), with each hydrogen getting 2 electrons (completing their duet).<\/li>\n\n\n\n<li>There are no unshared electrons (lone pairs) on silicon since all of its valence electrons are involved in bonding.<\/li>\n\n\n\n<li>Similarly, hydrogen atoms don\u2019t have any lone pairs either because they only need two electrons to be stable, which they achieve by sharing electrons with silicon.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Conclusion:<\/h3>\n\n\n\n<p>In the correct Lewis structure of SiH\u2084, all electrons are used in bonding. Silicon achieves an octet, and each hydrogen satisfies its duet. <strong>No lone pairs of electrons are present<\/strong> on either the silicon atom or the hydrogen atoms.
