Since there are two oxygen atoms, we have 12 valence electrons from oxygen.<\/li>\n\n\n\n<li>Fluorine (F) is also in Group 17, so it has 7 valence electrons.<br>Thus, the total number of valence electrons is:<\/li>\n<\/ul>\n\n\n\n<p>7(Cl)+12(O)+7(F)=26&nbsp;valence&nbsp;electrons.7 (\\text{Cl}) + 12 (\\text{O}) + 7 (\\text{F}) = 26 \\text{ valence electrons.}7(Cl)+12(O)+7(F)=26&nbsp;valence&nbsp;electrons.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2. <strong>Drawing the Lewis Structure<\/strong>:<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Chlorine will be the central atom since it is less electronegative than oxygen and fluorine.<\/li>\n\n\n\n<li>The two oxygen atoms and one fluorine atom will each form a single bond with chlorine.<\/li>\n\n\n\n<li>After the bonds, distribute the remaining electrons to complete the octet of oxygen and fluorine atoms.<\/li>\n\n\n\n<li>Chlorine, as a larger atom, will have more than 8 electrons around it in this case, which is allowed.<\/li>\n<\/ul>\n\n\n\n<p>After arranging the atoms and distributing the electrons, the Lewis structure will look like this:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Cl is single-bonded to each oxygen and fluorine.<\/li>\n\n\n\n<li>The oxygen atoms will have lone pairs to satisfy their octets.<\/li>\n\n\n\n<li>Fluorine will also have lone pairs.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">3. <strong>VSEPR Structure<\/strong>:<\/h3>\n\n\n\n<p>The VSEPR theory helps predict the molecular geometry by considering the regions of electron density around the central atom.
