Ionic Bonding Vs Covalent Bonding

Promoted by: Christi Wright

What Is Ionic Bonding?

Ionic Bonding is the transfer of valence electron(s) between two types of atoms.

Example Of Ionic Bonding:

The atom Oxygen needs (2) valence electrons to be just like the noble gas Neon.Calcium has (2) valence electrons that he wants to give away;calcium is going to give his (2) valence electrons to Oxygen so they both can be happy.They now have a special bond called Ionic bonding.

What is Covalent Bonding?

Covalent bonding is the sharing of electrons between atoms.

Example of Covalent Bonding:

There is a covalent bond between oxygen and hydrogen molecule in water (H2O).Each covalent bond contains two electrons- one from a hydrogen atom and one from the oxygen atom.

What are valence electrons and how do they relate to each type of bonding?

  • Valence electrons are the number of electrons that associate with an atom.
  • Valence electrons relate to Ionic bonding because valence electrons are taken from the less electronegative and the more electronegative atom receives them.
  • In covalent bonding ,the valence electrons are shared between the atoms.

How does periodic trends affect bonding?

Electronegativity- the ability of one atom to pull on electrons.

Explanation: The greater the difference between two atoms will allow one atom to completely take away the electron from the other atom which is ionic bonding ,but the lower the difference between the atoms ,that is when the atoms have to share electrons which is covalent bonding.
