It is influenced by two main factors:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Electron shielding:<\/strong> Electrons in inner shells can &#8220;shield&#8221; the outer electrons from the full attractive force of the nucleus.<\/li>\n\n\n\n<li><strong>Effective nuclear charge (Z_eff):<\/strong> This is the net positive charge experienced by an electron, calculated as the total nuclear charge minus the shielding effect of other electrons.<\/li>\n<\/ol>\n\n\n\n<h3 class=\"wp-block-heading\">Why Lithium Has a Larger Atomic Radius:<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Electron Configuration:<\/strong><\/li>\n\n\n\n<li>Lithium has the electron configuration <strong>1s\u00b2 2s\u00b9<\/strong>, meaning it has three electrons in total, with two in the first shell and one in the second.<\/li>\n\n\n\n<li>Neon has the electron configuration <strong>1s\u00b2 2s\u00b2 2p\u2076<\/strong>, meaning it has ten electrons, with two in the first shell and eight in the second.<\/li>\n\n\n\n<li><strong>Nuclear Charge:<\/strong><\/li>\n\n\n\n<li>Lithium has a nuclear charge of +3 (three protons), whereas Neon has a nuclear charge of +10 (ten protons).

This stronger pull draws the electrons closer to the nucleus, leading to a smaller atomic radius.<\/li>\n\n\n\n<li>In contrast, Lithium has a smaller effective nuclear charge, as it only has three protons.

Neon\u2019s higher nuclear charge results in a stronger attraction between the nucleus and electrons, pulling the electrons closer and reducing the atomic radius.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Between Li And Ne Which Element Has A Larger Atom And Why?
