  • They form cations in an aqueous solution.

Non-metals : Non-metals are the elements which can easily gain electrons and form an anion.

Properties of non-metals :

  • They are non-lustrous.
  • They are brittle and hard in nature.
  • They do not conduct heat and electricity.
  • The non-metallic oxides are acidic in nature.
  • They form anions in an aqueous solution.

Hence, from the given options the correct option for metal is, Malleable, shiny, and able to conduct heat or electricity.
