Question

How many single bonds can oxygen form?

Answer 1

2

Explanation:

Oxygen can form two single bonds because it has six valent electrons on its outer shell.
It is easier for an oxygen atom to accept or share two electrons instead of losing all six to become stable (Remember that stability involves having a filled outer shell. In this case, oxygen needs 8 electrons on its outer shell to be filled.).

So it can covalently double bond once or single bond twice
