Question

Which of the following is the correct representation of electron dot structure of oxygen?

• A. only (1)
• B. (1) and (4)
• C. (1) and (3)
• D. only (4)

Answer 1

The correct option is A only (1)

Oxygen has atomic no.8 and configuration is 2,6. Six electrons are in the outer shell which can combine with electrons of another atom. To complete its octet in outer shell oxygen needs two electrons which it can share with another oxygen atom forming a strong double bond in oxygen molecule.
