Nitrogen constitutes about 78% of the Earth&#8217;s atmosphere and is essential for life, though it is inert and non-reactive under normal conditions due to the strong triple bond between the nitrogen atoms.<\/p>\n\n\n\n<p>Let&#8217;s break down why nitrogen is a gas at room temperature compared to the other elements listed:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Nitrogen (N\u2082)<\/strong>: Nitrogen has weak intermolecular forces between its diatomic molecules, primarily van der Waals forces, which do not require much energy to overcome. As a result, nitrogen molecules remain in a gaseous state at room temperature (around 20-25\u00b0C). Its boiling point is -195.8\u00b0C, far below room temperature, which ensures that it stays as a gas under normal conditions.<\/li>\n\n\n\n<li><strong>Aluminum (Al)<\/strong>: Aluminum is a solid at room temperature with a melting point of about 660.3\u00b0C. As a metal, aluminum has a crystalline structure where its atoms are tightly bound in a lattice by metallic bonds, which gives it a solid state.<\/li>\n\n\n\n<li><strong>Potassium (K)<\/strong>: Potassium is an alkali metal that is also solid at room temperature, though it has a lower melting point compared to many other metals (63.5\u00b0C). Potassium has metallic bonds that maintain its solid form until higher temperatures.<\/li>\n\n\n\n<li><strong>Sodium (Na)<\/strong>: Similar to potassium, sodium is another alkali metal that is solid at room temperature. It has a melting point of 97.8\u00b0C and remains solid under normal conditions. Like potassium, sodium\u2019s metallic bonds keep it in a solid state at room temperature.<\/li>\n<\/ul>\n\n\n\n<p>In summary, nitrogen is a gas at room temperature due to its weak intermolecular forces and low boiling point, while aluminum, potassium, and sodium are solids due to their strong metallic bonding structures.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Which is a gas at room temperature?A) aluminumB) nitrogenC) potassiumD) sodium The Correct Answer and Explanation is: The correct answer is B) nitrogen.
