1. The problem statement, all variables and given/known data state whether or not these ions have electron configurations of a noble gas: Na+, H-,O2- 2. Relevant equations 3. The attempt at a solution I said yes to all three. Because Na+ and O2- has electron configuration of Neon. H- has electron configuration of Helium. If I'm wrong, please correct me and explain to me about it. Thank you so much for yall time!
