To name this compound correctly using <strong>IUPAC (International Union of Pure and Applied Chemistry)<\/strong> nomenclature, several rules must be followed, particularly because iron is a <strong>transition metal<\/strong> that can form more than one type of positive ion (cation).<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">1. <strong>Identify the ions and their charges:<\/strong><\/h4>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Oxygen<\/strong> usually forms a <strong>-2<\/strong> ion (O\u00b2\u207b).<\/li>\n\n\n\n<li>In FeO, there is one iron atom and one oxygen atom. Since oxygen has a charge of -2, the iron must have a charge of <strong>+2<\/strong> to balance the compound to neutral. So, the iron ion here is <strong>Fe\u00b2\u207a<\/strong>.<\/li>\n<\/ul>\n\n\n\n<h4 class=\"wp-block-heading\">2. <strong>Name the metal with its oxidation number:<\/strong><\/h4>\n\n\n\n<p>Because iron can have multiple oxidation states (Fe\u00b2\u207a and Fe\u00b3\u207a), the name must specify which form is present. This is done using <strong>Roman numerals<\/strong> in parentheses immediately after the name of the metal.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Fe\u00b2\u207a is called <strong>Iron(II)<\/strong><\/li>\n\n\n\n<li>Fe\u00b3\u207a is called <strong>Iron(III)<\/strong><\/li>\n<\/ul>\n\n\n\n<p>Since the Fe in FeO is Fe\u00b2\u207a, we name it <strong>Iron(II)<\/strong>.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">3. <strong>Name the non-metal as an -ide:<\/strong><\/h4>\n\n\n\n<p>The anion (O\u00b2\u207b) is named as &#8220;oxide&#8221;.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">4. <strong>Put it all together:<\/strong><\/h4>\n\n\n\n<p>Combining the cation and anion names gives us <strong>Iron(II) oxide<\/strong>.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">Why Other Options Are Incorrect:<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>A) iron oxide<\/strong> \u2013 Incomplete and ambiguous.
