Rubidium

A chemical element with the symbol Rb and atomic number 37, part of the alkali metal group. It is a soft, silvery-white metallic element that is highly reactive, especially with water, and must be stored under specific conditions to prevent reactions with air. Rubidium is used in atomic clocks, research and development in electronics and materials science, and the production of special glasses, benefiting scientists and industries requiring precise timekeeping and advanced materials.
