ZINC 
Zinc is another of the useful metals that we use every day. It's one of those elements humans have been using for thousands of years. You'll find zinc in minerals, alloys, and even your body. It wasn't ever really discovered, zinc was used long ago when ancient peoples were first creating brass. In 1746, Marggraf was isolated and described zinc as a separate metal. Zinc is normally found as a part of larger mineral compounds. When isolated, it is a very shiny, bluish-white metal. Unfortunately, it is not as malleable as its neighbor copper is and has fewer uses. If you have been reading about all of the elements, you should be excited to know that zinc is the last transition element in the fourth period/row on the table of elements. Zinc's location at the end of the transition metals shows that is has a completely filled third electron shell.
