Hey friend....
Ur ans is.....
The physical properties of alkali metals are
•They are silvery white in color.
They are soft and light metals.
•Their density decreases while moving down the groups.
•They have only one electron in their outermost shell.
•They have very weak bond.
•They have low melting and boiling point.
The chemical properties of alkali metals are
•They are radioactive towards air.
•Alkali metals are a strong reducing agent.
•Alkali metals are soluble in liquid ammonia and form a blue solution which is conducting in nature.
•Alkali metals react vigorously with halogens to form ionic halides M+X–.
•At 673 K, alkali metals reacts with dihydrogen to form hydrides.
HOPE THIS'LL HELP U.
