a gas having property same as alkali metal
Answers
Answer:
They are lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr). (Like the other elements in Group 1, hydrogen (H) has one electron in its outermost shell, but it is not classed as an alkali metal since it is not a metal but a gas at room temperature.) Periodic Table of the Elements.
The alkali metals have played an important role in quantum physics. Some alkali metal isotopes, such as rubidium-87, are bosons. Dilute atomic gases of such alkali metal isotopes, confined by magnetic fields or “laser mirrors” and cooled to temperatures near absolute zero, form Bose-Einstein condensates. In this state, the cluster of atoms is in a single quantum state and exhibits macroscopic behaviours normally seen only with atomic-sized particles.
Lithium, the lightest of the alkali metals, is the only alkali metal which reacts with nitrogen at standard conditions, and its nitride is the only stable alkali metal nitride. Nitrogen is an unreactive gas because breaking the strong triple bond in the dinitrogen molecule (N 2 ) requires a lot of energy.
