Concept:

 

The distribution of electrons in different orbitals is called electronic configuration. The electrons filled in the outermost shell are called valence electrons.

 

Electron dot diagram or Lewis dot diagram is a representation of an atom in which the valence electrons are shown as dot around the letter symbol of the element.

Solution:

 

Step 1: The letter symbol for oxygen is ‘O’.

 

 

Step 2: The electronic configuration of oxygen is . The electrons present in the highest principal energy level are valence electrons. The number of valence electrons for oxygen atom is 6.

 

Step 3: Distribute the valence electrons around the oxygen atom.
