Step 1:I'll solve this problem step by step following the specified LaTeX formatting guidelines:
Step 2:: Identify the element
- The problem involves the oxygen ion $$O^{2-}
- Oxygen is located in Group 16 (or Group VIA) of the periodic table
Step 3:: Determine the electron configuration of neutral oxygen
- Valence electrons in neutral oxygen: $$2s^{2} 2p^{4}$$ (6 electrons)
- Neutral oxygen's atomic number is 8
Step 4:: Calculate valence electrons in O^{2 -} ion
- Add 2 more electrons: $$6 + 2 = 8$$ total valence electrons
- Starting with 6 valence electrons
Final Answer
There are 8 electrons in the valence shell of the O^{2 -} ion.
