class=\"wp-block-heading\">Concept<\/h2>\n\n\n\n<p class=\"has-medium-font-size\"><strong>Metallic character<\/strong> Of Elements refers to an atom\u2019s tendency to <strong>lose electrons<\/strong> and form <strong>positive ions<\/strong>.<br>For example:<\/p>\n\n\n\n<p class=\"has-medium-font-size\"><strong>Mg \u2192 Mg\u00b2\u207a + 2 electrons<\/strong><\/p>\n\n\n\n<p

energy<\/strong><\/li>\n<\/ol>\n\n\n\n<ul class=\"wp-block-list\">\n<li class=\"has-medium-font-size\">Atoms with <strong>larger size<\/strong> and <strong>lower ionization energy<\/strong> lose electrons more easily, making them <strong>more metallic<\/strong>.<\/li>\n\n\n\n<li class=\"has-medium-font-size\">In contrast, <strong>smaller atoms<\/strong> with high ionization energy tend to hold onto electrons more tightly, showing <strong>less metallic character<\/strong>.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Periodic Trends In Metallic Character Of Elements :Across a Period<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li class=\"has-medium-font-size\">As you move from left to right in a period, <strong>atomic size decreases<\/strong>.<\/li>\n\n\n\n<li class=\"has-medium-font-size\">The <strong>number of protons increases<\/strong>, which increases the <strong>effective nuclear charge (Z_eff)<\/strong>.<\/li>\n\n\n\n<li class=\"has-medium-font-size\">This stronger nuclear attraction <strong>pulls electrons more tightly<\/strong>, making it harder for atoms to lose electrons.<\/li>\n\n\n\n<li class=\"has-medium-font-size\">As a result, <strong>ionization energy increases<\/strong>, and <strong>metallic character decreases<\/strong>.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Observation :<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li class=\"has-medium-font-size\"><strong>Nonmetals<\/strong> like F, O, Cl, and N, located on the far right of the periodic table, are the <strong>least metallic<\/strong>.<\/li>\n\n\n\n<li class=\"has-medium-font-size\"><strong>Alkali metals<\/strong> (Group 1) show the <strong>highest metallic character<\/strong> in each period.<\/li>\n\n\n\n<li class=\"has-medium-font-size\"><strong>Alkaline earth metals<\/strong> (Group 2) are also reactive but slightly less than alkali

class=\"has-medium-font-size\">Moving down a group, <strong>atomic size increases<\/strong> as atoms gain more electron shells.<\/li>\n\n\n\n<li class=\"has-medium-font-size\">Even though protons are added, the increase in distance and <strong>shielding effect<\/strong> reduces Z_eff.<\/li>\n\n\n\n<li class=\"has-medium-font-size\">As a result, atoms <strong>lose electrons more easily<\/strong>, and their <strong>metallic character increases<\/strong>.<\/li>\n\n\n\n<li class=\"has-medium-font-size\"><strong>Ionization energy decreases<\/strong> down the group, supporting easier electron
