Question

Lewis structure for the ionic compound potassium chloride

Answer 1

The Lewis structure for potassium chloride represents potassium and chlorine as ions, K+ and Cl-, without shared electrons, due to their ionic bonding.

Step-by-step explanation:

The question pertains to the Lewis structure for the ionic compound potassium chloride (KCl). In the Lewis structure for KCl, potassium (K) donates one electron to chlorine (Cl), forming a potassium cation (K+) and a chloride anion (Cl-). The resulting structure is not typically drawn as a Lewis dot structure because it represents ionic bonds as an electrostatic attraction, rather than sharing electrons in a molecular bond. The ionic forces in KCl are strong, making it a solid at room temperature. Potassium chloride dissolves in water, with the polar water molecules hydrating the ions, as depicted in the provided figures.

Answer 2

The Lewis structure for potassium chloride (KCl), which is an ionic compound, cannot be represented by a single Lewis structure. Ionic compounds do not have a covalent bond, instead they have an electrostatic attraction between positive and negative ions. In the case of potassium chloride, potassium (K) has a charge of +1 and chloride (Cl) has a charge of -1. The ionic compound can be represented by showing the positive and negative ions next to each other, separated by a dash or an arrow, like this:

K+ Cl-

Step-by-step explanation:

Alternatively, it can be represented by a crystal lattice structure, which shows the repeating pattern of positive and negative ions in the solid compound.
