Is Ca the most active element?

What does sound most slowly travel through a metal pole a wood block a pool of water or an area of cool air?

Which is the most reative metal?
The most reactive metal is francium. Francium is a highly unstable alkali metal and is usually found in trace amounts in uranium and thorium ores. It readily reacts with air and water, making it one of the most reactive elements known.

What chemical properties does lead have?
Lead is a moderately active metal. It dissolves slowly in water and in most cold acids. It reacts more rapidly with hot acids. It does not react with oxygen in the air readily and does not burn.
Sodium is called an active metal.why?
Sodium is considered an active metal because it is highly reactive with other elements due to its tendency to donate its one valence electron to form stable compounds. This reactivity can lead to vigorous reactions when sodium comes into contact with water or air, making it an active metal.
