Copper nickels.

This is a chart of the most common charges for atoms of the chemical elements. You can use this chart to predict whether or not an atom can bond with another atom.The charge on an atom is related to its valence electrons or oxidation state.An atom of an element is most stable when its outer electron shell is completely filled or half-filled.In fact, for most of 1942, the 5-cent coin was made from nickel. In October, this changed, since nickel was needed to make artillery for troops in World War II. Also worth noting… silver nickels aren’t made entirely from silver.
