Frequently Asked Questions

Why are metals good conductors of electricity?

Metals have free electrons that move easily through their crystalline structure, allowing them to conduct electricity.

How does the reactivity series help predict reactions between metals and acids?

The reactivity series shows the order of reactivity of metals, with more reactive metals reacting faster and more vigorously with acids.
