Oxygen (O) and Nitrogen (N) are both nonmetals found in group 15 and 16 of the periodic table, respectively, indicating their roles as essential elements in biological processes. Oxygen has an atomic number of 8 and is located in period 2, while Nitrogen has an atomic number of 7 and is also in period 2. One of the primary differences between them is that Oxygen has a higher electronegativity than Nitrogen, which makes it more reactive and capable of forming stronger bonds, particularly in combustion and oxidation reactions. Both elements are diatomic gases at room temperature (O₂ and N₂), but Oxygen is essential for respiration in aerobic organisms, while Nitrogen, while abundant in the atmosphere, is mostly inert and is primarily used in the formation of amino acids and nucleic acids in biological systems. Their similar positions in the periodic table reflect their comparable atomic structures, yet their differing properties underscore their unique roles in chemistry and biology.
Find Oxygen (O) and Nitrogen (N) on the periodic table provided below. In 3-5 sentences, compare and contrast the two elements. Describe the characteristics that make Oxygen different from Nitrogen and the characteristics that make Oxygen similar to Nitrogen. Things to consider would include, but not be limited to, their atomic structure and position on the periodic table.

Oxygen (O) and Nitrogen (N) are both nonmetals located in period 2 of the periodic table, with atomic numbers 8 and 7, respectively. A key difference is that Oxygen is more electronegative and reactive compared to Nitrogen, which makes it vital for processes like respiration. Both elements are diatomic gases at room temperature—O₂ and N₂—but while Oxygen supports life, Nitrogen is mostly inert in the atmosphere. Their similar positions reflect comparable atomic structures, yet they fulfill distinct roles in chemistry and biology.
