What are 3 facts about alkali metals?

Interesting Facts about Alkali Metals
  • Because they are so reactive with air and water, they are generally stored in oil.
  • Cesium and rubidium are used to make atomic clocks.
  • Sodium and potassium both play an important role in biological life on Earth.
  • Sometimes cesium is also spelled "caesium."

Similarly, what is special about alkali metals?

The alkali metals consist of the chemical elements lithium (Li), sodium (Na), potassium (K), rubidium (Rb), caesium (Cs), and francium (Fr). The alkali metals are all shiny, soft, highly reactive metals at standard temperature and pressure and readily lose their outermost electron to form cations with charge +1.

what are alkali metals for kids? Alkali metals are six chemical elements that form the first group of elements in the periodic table. These six elements are lithium, sodium, potassium rubidium, cesium, and francium. Three elements of this group which are rubidium, cesium, and francium are extremely rare elements.

Similarly, what are three properties of alkali metals?

Characteristics of alkali metals are:

  • High reactive metals.
  • Not found freely in nature.
  • Stored in a mineral oil solution.
  • Low melting points.
  • Low densities (lower than other metals)
  • Low electronegativity.
  • Low ionization energy.
  • React easily with halogens.

What is the first alkali metal?
