By observing the Bohr Models for the elements Potassium and Nitrogen below, Potassium has valence electron(s) and Nitrogen has valence electron(s). If these two substances were form an ionic bond in a chemical reaction, the resulting chemical formula for the substance produced (Potassium Nitride) would have Potassium atom(s) and Nitrogen atom(s).
Question
By observing the Bohr Models for the elements Potassium and Nitrogen below, Potassium has valence electron(s) and Nitrogen has valence electron(s). If these two substances were form an ionic bond in a chemical reaction, the resulting chemical formula for the substance produced (Potassium Nitride) would have Potassium atom(s) and Nitrogen atom(s).
Solution
The Bohr model for Potassium (K) shows that it has 1 valence electron in its outermost shell, while Nitrogen (N) has 5 valence electrons in its outermost shell.
In an ionic bond, atoms transfer electrons to achieve a full outer shell, typically of 8 electrons, to become more stable. Potassium, with 1 valence electron, will want to lose that electron. Nitrogen, with 5 valence electrons, will want to gain 3 electrons to have a full outer shell.
Therefore, in the formation of Potassium Nitride, three Potassium atoms will each give their 1 valence electron to one Nitrogen atom. This results in the Nitrogen atom having a full outer shell and each Potassium atom having a full outer shell (since the next inner shell becomes the outermost shell when the electron in the outermost shell is lost).
So, the chemical formula for Potassium Nitride would be K3N, indicating 3 Potassium atoms and 1 Nitrogen atom.
