What is the electronic configuration of the nitrogen atom?
Step 1: Understand that nitrogen is an element with the atomic number 7, which means it has 7 protons and 7 electrons.
Step 2: Electrons are arranged in energy levels or shells around the nucleus of the atom.
Step 3: The first energy level can hold a maximum of 2 electrons. So, we fill this level first: 1s2 (2 electrons in the 1s orbital).
Step 4: The second energy level can hold a maximum of 8 electrons. We fill the 2s orbital next: 2s2 (2 electrons in the 2s orbital).
Step 5: After filling the 1s and 2s orbitals, we have 3 electrons left to place in the 2p orbital. We fill the 2p orbital: 2p3 (3 electrons in the 2p orbital).
Step 6: Combine all the filled orbitals to write the complete electronic configuration: 1s2 2s2 2p3.
