Nitrogen: Understanding Its Electronic Configuration And Role In Biology
Nitrogen, vital in biology, has an atomic number of 7, corresponding to seven electrons distributed in energy levels. Its electron configuration, 1s²2s²2p³, reveals unpaired electrons in the 2p sublevel following Hund’s rule. The Pauli exclusion principle ensures these electrons’ unique quantum states. Nitrogen’s three unpaired 2p electrons result from its seven total electrons, the maximum…
