The cohesive energy of NaCl is - 7.90 eV, with a Coulomb contribution of -8.85 eV, a repulsive contribution of 1.02 eV, a van der Waals contribution of - 0.125 eV, and a term due to the zero point ...

The reaction releases a lot of heat as the ionic compound sodium chloride is formed. A sodium and chlorine atom ... The +2 calcium ion and the two -1 chloride ions attract each other and form an ionic ...

That's the opposite of rare. Other elements can bond with diatomic elements to form diatomic molecules. That's how we get table salt (sodium + chlorine = NaCl, sodium chloride). You can find a ...

Elements bond in fixed ratios and so can be represented by a chemical formula. For example, sodium chloride has the same number of sodium ions and chloride ions, so its formula is NaCl ...
