Sodium is a medal and chlorine is a poisonous gas. Neither is safe to eat. However, when sodium and chlorine is combine, it produces edible table salt. What can be concluded?
1) Table salt has similar physical properties of both reactants.
2)Table salt is a metalloid with properties of both reactants.
3)Other ingredients have been added to make table salt safe.
4)products are chemically different from reactants.

I think it is #1, can you confirm?
Thanks
