Guida verificata passo dopo passo1
Step 1: Identify the atomic number of nitrogen, which is 7. This means a neutral nitrogen atom has 7 electrons.
Step 2: Recall the order in which electron orbitals are filled according to the Aufbau principle: 1s, 2s, then 2p.
Step 3: Fill the 1s orbital first with 2 electrons: \$1s^2$.
Step 4: Next, fill the 2s orbital with 2 electrons: \$2s^2$.
Step 5: Distribute the remaining 3 electrons in the 2p orbitals, giving \$2p^3$. So, the full electron configuration is \$1s^2 2s^2 2p^3$.
