The structure is composed of a series of dots, one for each atom, with lines connecting the dots to represent the bonds between them. The order of the atoms is based on their chemical symbols, with the atoms on the left of the structure being the most to the right being the least electronegative.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"How_to_Draw_Lewis_Structure\"><\/span>How to Draw Lewis Structure<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The Lewis structure for ICl can be drawn by placing one chlorine atom on the left side of the iodine atom, and then drawing a single bond between them. A second chlorine atom can then be placed on the right side of the iodine atom, and then drawn with a single bond to the iodine atom.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Formal_Charge_Formula\"><\/span>Formal Charge Formula<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The formal charge of an atom is a measure of the electron-pair repulsion within an atom. The formal charge of an atom is calculated by subtracting the number of electrons in the outermost shell from the number of protons in the nucleus. The formal charge of an atom is always a negative number.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Let_us_Now_Calculate_the_Formal_Charge_for_SO4-2\"><\/span>Let us Now Calculate the Formal Charge for SO4-2<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The formal charge for SO4-2 is +2.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Importance_of_Formal_Charge\"><\/span>Importance of Formal Charge<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The formal charge of an atom is a measure of how many electrons an atom has lost, gained, or shared in order to achieve a stable octet of electrons. The formal charge of an atom is calculated by subtracting the number of electrons assigned to the atom from the number of electrons assigned to the atom&#8217;s highest occupied molecular orbital (HOMO). The formal charge of an atom is also equal to the number of protons in the nucleus minus the number of electrons in the nucleus.<\/p>\n<p>The formal charge of an atom is important because it can be used to determine the stability of a molecule. A molecule is more stable when the formal charges of its atoms are as close to zero as possible.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Real_Molecules_Vs_Lewis_Structures\"><\/span>Real Molecules Vs Lewis Structures<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>There are several major differences between molecules and Lewis structures. The most obvious difference is that molecules are three-dimensional, while Lewis structures are two-dimensional. Molecules also have much more complex shapes than Lewis structures.
