To understand its shape, we can apply the <strong>Valence Shell Electron Pair Repulsion (VSEPR)<\/strong> theory. This theory states that electron pairs around a central atom will arrange themselves as far apart as possible to minimize repulsion.<\/p>\n\n\n\n<p>In NH\u2083, nitrogen is the central atom. It has five valence electrons, and it forms three single covalent bonds with hydrogen atoms. This uses up three of the five electrons, leaving one <strong>lone pair<\/strong> of electrons on nitrogen. Therefore, there are <strong>four regions of electron density<\/strong> (three bonding pairs and one lone pair) around the nitrogen atom.<\/p>\n\n\n\n<p>According to VSEPR theory, four regions of electron density arrange themselves in a <strong>tetrahedral<\/strong> geometry to minimize repulsion. However, since one of these regions is a lone pair (which takes up more space than bonding pairs), the actual <strong>molecular shape<\/strong> becomes <strong>trigonal pyramidal<\/strong> rather than tetrahedral.<\/p>\n\n\n\n<p>The lone pair pushes the bonding pairs closer together, reducing the <strong>bond angle<\/strong> from the ideal tetrahedral angle of <strong>109.5\u00b0<\/strong> to about <strong>107\u00b0<\/strong>. This smaller bond angle is a direct result of the lone pair\u2019s greater repulsive force.<\/p>\n\n\n\n<p>In a diagram, the nitrogen atom would appear at the center, with three hydrogen atoms arranged in a triangle-like base, and the lone pair positioned above nitrogen. The overall shape looks like a pyramid with a triangular base.<\/p>\n\n\n\n<p>To summarize, NH\u2083 has a <strong>trigonal pyramidal shape<\/strong> due to three bonding pairs and one lone pair on nitrogen. The bond angle is <strong>approximately 107\u00b0<\/strong>, slightly less than the tetrahedral angle because of the lone pair repulsion.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"1024\" src=\"https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner5-149.jpeg\" alt=\"\" class=\"wp-image-30466\" srcset=\"https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner5-149.jpeg 1024w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner5-149-300x300.jpeg 300w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner5-149-150x150.jpeg 150w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner5-149-768x768.jpeg 768w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Draw and state the molecular shape of NH3.
