Question

What is the ionic bonding between Potassium and Fluorine?

Answer 1

Hint :Ionic bond is also known as electrovalent bond. It is a type of bond in which electrons get transferred from one atom to another permanently and each atom gets negative or positive charge depending upon whether they donated or accepted electrons.

Complete Step By Step Answer:
In this, a potassium atom has one valence electron in its valence shell which is the outermost shell of an atom. Whereas, fluorine has seven valence electrons in the outermost shell so potassium donates its one valence electron to get stable as it now has eight electrons in third energy level. Now, after accepting one electron from potassium fluorine has eight electrons in its outermost shell to get stable. This will produce potassium cation and fluorine anion.
This oppositely charged ions will result in electrostatic attraction which we call it as ionic bond. The compound which is made through ionic bonding is potassium fluoride. That is ($KF$). The compound is in neutral state but not the individual ions in the compound.

Note :
In chemistry, ionic bonds play a very important role in chemistry because they allow the synthesis of specific organic compounds. Ionic bonds are the strongest bond than other bonds. It is due to coulombic attraction between ions of opposite charges.
