What is an active metal?

Active metals refer to metals that readily react with other substances, particularly in aqueous environments. These metals are primarily found in group 1 and group 2 of the periodic table, such as lithium, sodium, potassium, and calcium.

One characteristic of active metals is their ability to easily lose electrons, which makes them highly reactive. This reactivity is due to their low ionization energies and ability to form stable ionic compounds with non-metals.

Active metals are commonly used in various industrial applications, such as in the production of batteries, fireworks, and metal alloys. They are also used in the manufacturing of pharmaceuticals, fertilizers, and other chemical products.

One potential downside of active metals is their propensity to corrode or tarnish when exposed to air or moisture. This is why they are often stored in inert environments or coated with protective layers to prevent reactions with the surrounding environment.

Overall, active metals play a crucial role in many sectors of industry and have unique properties that make them valuable resources in various applications.
