Potassium has a 1 + charge, and oxygen has a 2 - charge. A Lewis dot diagram should contain two potassium atoms and one oxygen atom to show how these atoms form an ionic bond.

True or false

The answer is: True

I took the quiz and it was correct.

False

Explanation:

A Lewis dot diagram applies only to covalent bonds. G. N Lewis developed the idea of covalent bonds in the early 20th century. The sharing of electrons between covalent molecules is usually represented by dot structures which later came to be widely known as Lewis structures.

These structures cannot be applied to ionic compounds since there isn't any sharing of electrons in ionic bonds.
