Calculate the amount of energy released when Na plus and Cl minus ions originally at infinite distance apart are brought close together at a distance of 2.76 Angstrom. Assume that ions act as point charges with 1.6 × 10 power -19 coulomb.( K = 9 × 10 power 9 NM square/coulomb square) I will give 10 points
