Problem- When a metal atom becomes an ion, or an ion becomes an atom, there is a transfer of electrons. In the preceding reactions, draw circles around the metal atoms which lost electrons and boxes around the metal ions which gained them (reactants).

1. Which is more active: (a) iron or copper, (b) iron or silver, (c) silver or copper? Arrange the three metals in order of decreasing activity.

2. Arrange all of the metals tested in all parts of this experiment, including hydrogen, in order of decreasing activity

Explain the each step. Explain the process and each step.
