List some characteristic properties that distinguish die metallic elements from the nonmetallic elements.

Interpretation Introduction

Interpretation:

Some characteristic properties that distinguish the metallic and non metallic element has to be listed.

Concept introduction:

On chemical reaction, the element which is able to form positively charged ion (cation) by losing an electron called metal. While the element which is able to form negatively charged ion (anion) by gaining an electron called non-metal.

Explanation of Solution

Explanation

Physical properties of metal

  • State: At room temperature, metals are solid except Mercury which is in liquid form at room temperature.
  • Ductility: Metals are strained into wires.
  • Hardness:  Mostly metals are hard except Sodium and Potassium they are soft.
  • Melting point and Boiling point:  Metal have greater melting and boiling point.
  • Conduction: Generally, metals are good conductor because they have free electrons.

Chemical properties of metal

  • Metals are said to be electropositive elemets they form base or amphoteric oxides when react with Oxygen.

    Metals tend to have less ionization energy and it loses an electron when chemical reaction. Hence it does not accept electrons.

Example:

Na0Na++ e-

Physical properties of non metal

  • State: At room temperature, non metals are exist in gas and solid state.
  • Ductility: Non metals are easily broken
