Add electron dots and charges as necessary to show the reaction of potassium and bromine to form an ionic compound

Explanation: Electron dot structures are the lewis dot structures which represent the number of valence electrons around an atom in a molecule.

The electronic configuration of potassium is

Valence electrons of potassium are 1.

The electronic configuration of Bromine is

Valence electrons of bromine are 7.

These two elements form ionic compound.

Ionic compound is defined as the compound which is formed from the complete transfer of electrons from one element to another element.

Here, one electron is released by potassium which is accepted by bromine element. In this process, Potassium becomes cation having +1 charge and Bromine become anion having (-1) charge.

The ionic equation follows:

The electron dot structure is provided in the image below.
