$\huge\underline\mathfrak\red{Answer}$ $\huge\orange{Halides\:Of\:Alkali\:Metals}$

• The alkali metal halides are all high melting.
• They are colourless crystalline solids.
• All the halides have negative enthalpies formation.
• All halides are soluble in water.

Answer 2

alkali metal halide are electrostatic in nature as the bond between alkali metal and its halide are electrostatic .they are generally salt like Nacl ,kCl etc .

These salts are formed by the reaction with hydroxide of alkali metal with acid .

eg

HCl + NaoH /KoH (alkali metal hydroxide ) ------> Nacl + H2O

this reaction is called neutralization reaction.

oxidation number of which alkali metal is +1 .
