Frank, yes calcium is one of the metals that combines with
negative ion oxygen and partcipates out. The negative ion
oxygen combines with the positive iron ion to make rust.
I guess zinc stays in solution. Thanks for setting me straight.
The zinc plate genetates a current that flows into the zinc
and out of the iron. That disovles the zinc and keeps the iron
from ionizing since electrons are forced on the iron.
