down's process- produce sodium from NaCl(products of it must be separate to prevent recombination)

down the group:
  • atomic number +
  • enthalpy atomization -
  • mp -
  • bp-
  • first ionization energy,IE -
  • radius +
  • cation size +
all metals- body centered cubic structure

appearance-Li,Na,K,Rb:silvery white-Cs:golden yellow        (all soft)
