Question

In three to five sentences, identify the type of bonding that would form between potassium (K) and chlorine (Cl). Use electronegativity to justify this bond type. Provide the chemical formula for the resulting compound.
(two sentences is good enough tbh)

Answer 1

Answer:

when potassium reacts with chlorine, the former loses its valence electron and the latter takes it. The two resulting ions, i.e. the potassium cation and the chloride anion, are then bonded together by the electrostatic force of attraction → an ionic bond is formed.

Explanation:

Answer 2

The type of bonding that would form between potassium (K) and chlorine (Cl) is ionic bonding.

• The oppositely-charged ions formed $K^+ \text{and } Cl^-$, are then strongly attracted to each other by strong electrostatic forces in the crystal lattice, called ionic bonds.
• The chemical formula for the resulting compound i.e. Potassium chloride is $KCl$.

In terms of electronegativity: Since, It determines how the shared electrons are distributed between the two atoms in a bond.

• The more strongly an atom attracts the electrons in its bonds, the larger its electronegativity.

• Electronegativity of $KCl$ is 2.2 which is ionic.
