GPT 3.5
A. CaS has smaller energy than BaS. This is because calcium (Ca) is smaller in size and has a lower charge than barium (Ba), resulting in weaker electrostatic forces between the ions in CaS compared to BaS.
B. NaF has smaller energy than MgO. This is because sodium (Na) and fluorine (F) have smaller charges and are smaller in size compared to magnesium (Mg) and oxygen (O), resulting in weaker electrostatic forces between the ions in NaF compared to MgO.
