I believe the answer is Exothermic
Answer:
If it loses to electrons the net charge will be +2. If the atom instead gains 4 electrons, the net charge will be -4.
Explanation: When an atom loses electrons( which are negatively charged), it turns into a cation. This means since there is more protons(which are positively charged) than electrons, the charge is positive. The charge is positive and than the number of electrons lost. It is the exact opposite for gaining electrons.
chlorine has the atomic mass of 35.5 and is a non metal in the halogen family
General 'rule' - "like dissolves like". The solubility
of a solute in a solvent (that is, the extent of the mixing of the
solute and solvent species) depends on a balance between the natural
tendency for the solute and solvent species to mix and the tendency for a
system to have the lowest energy possible.
Hope this helps :p
