use the periodic table to answer the following questions. how many valence electrons does oxygen have? 6 complete type in the correct values to correctly represent the valence electron configuration of oxygen: as^b2p^c a = b = c = what is the charge of an oxygen ion? done
Answer
Explanation:
Step1: Recall oxygen's position
Oxygen is in the second - period and group 16.
Step2: Determine valence electron configuration
The general form for second - period elements' valence electron configuration is $ns^n2p^m$. Oxygen has 2 electrons in the 2s orbital and 4 electrons in the 2p orbital. So for $As^B2p^C$, $A = 2$, $B = 2$, $C = 4$.
Step3: Find oxygen ion charge
Oxygen wants to gain 2 electrons to achieve a stable octet. So the charge of an oxygen ion is - 2.
Answer:
A = 2 B = 2 C = 4 Charge of oxygen ion: - 2
