    It depends on their form:

    1. solid metals are a separate phase, they create a deposit

    2. salts over a certain concentration, part create a deposit, so they slowly create a powder at the bottom, part stay in solution as ions

    3. Ionic metal in solutions spreads all over, as any concentration difference (gradient) generates an excess of free energy that the system naturally releases. You need to add external energy to maintain the gradient, such as a external electric potential gradient (an anode and a cathode)
