Question

draw this o₂ molecule and label the two types of electron areas you see (lone pairs and bonds). how many valence electrons does each oxygen feel like it has now that they have bonded together?
6
8
4

Explanation:

Step1: Analyze oxygen's valence - electron situation

Oxygen has 6 valence electrons initially. In an $O_2$ molecule, the two oxygen atoms form a double - bond ($O = O$). Each oxygen atom also has two lone pairs of electrons.

Step2: Calculate valence electrons after bonding

Each oxygen atom in the $O_2$ molecule has 4 non - bonding electrons (2 lone pairs) and 4 bonding electrons (in the double - bond). So, $4 + 4=8$ valence electrons per oxygen atom.

Answer:

8
