For each of the following, write the electron configuration for each element on the reactants side. Then write the electron configuration for the ions that would be formed when making the ionic compound product. (You may use noble gas core configurations) Example: Sodium and chlorine Na+Cl→Na1++Cl1- →NaCl 1s22s22p63s1 + 1s22s22p63s23p5 → 1s22s22p6 + 1s22s22p63s23p6 → NaCl Calcium and fluorine Potassium and sulfur Magnesium and oxygen Zinc and nitrogen Lithium and bromine 6. Iron(III) and chlorine 7. Nickel(II) and nitrogen 8....
