alkali metals

Presents an introduction to elements known as alkali metals, explaining why they are soft and have low melting points and densities compared to other metals but are powerful in other ways and includes a segment on fireworks illustrating their explosive traits.

Describes the properties and industrial uses of sodium, lithium, potassium, rubidium, cesium, and francium, discussing the reactivity trend in the alkali metals, their reactions with water, their flame test colors, and everyday objects made from them.

The alkali metals are a fascinating group of six elements that are necessary to life on Earth. The Alkali Metals explores the original discovery of these six elements, how they are classified on the periodic table, compounds, uses, and how these elements impact the reader individually.
