One type of chemical process that can be either exothermic or endothermic is dissolving of salts in water. A salt is a compound made up of positively charged ions and negatively charged ions which are held together in a solid state because the positive and negative charges attract one another.
In the center, there would be Carbon with four valence electrons, one on each side.
Then, surrounding the Carbon atom, would be a Chlorine atom to each valence electron. Since Chlorine has 7 valence electrons, it would have six surrounding it and the lone valence electron connected to each valence electron on each side of the Carbon atom.
Hope this helps!
