其它碱金属包括氢(技术上说不是种金属)，锂，钠，钾，铷，铯。
Other Alkali Metals include Hydrogen (technically not a metal), Lithium, Sodium, Potassium, Rubidium, and Cesium.
碱：无机化合物，任何碱金属，即锂、钠、钾、铷、铯的可溶氢氧化物。
Alkali: Inorganic compound, any soluble hydroxide -oh. of the alkali metals: lithium, sodium, potassium, rubidium, and cesium.
实验上常常选择铯、铷等能级结构相对简单的碱金属原子来研究光与原子的相互作用。
Cesium, rubidium or other alkali metal atoms with simple energy level structure often are used in experiments to study the interaction between light and atoms.
