Guida verificata passo dopo passo1
Step 1: Identify the atomic number of boron, which is 5. This means boron has 5 electrons to place in its electron configuration.
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: Place the remaining 1 electron in the 2p orbital: \$2p^{1}$. Thus, the electron configuration is \$1s^{2} 2s^{2} 2p^{1}$.
