Question

what property distinguishes metals from non-metals??

Answer 1

Answer:

Properties of Metals

Physical Properties of Metals

1. Shiny (lustrous) in nature

2. Metal is a good conductor of electricity and heat

3. Density and melting point is high

4. Mouldable (Malleable)

5. Ductile

6. At room temperature, it is in solid form except for mercury

7. Opaque

Chemical Properties of Metals

1. Easily corrodible

2. Can lose electrons

3. Form basic oxides

4. Have low electronegativities

5. Good reducing agents

Properties of Non-Metals

Physical Properties of Non-metals

1. Poor conductors of electricity and heat

2. Non-Ductile metals

3. Brittle solids

4. Maybe solids, liquids or gases at room temperature

5. These are not sonorous

6. Transparent

Chemical Properties of Non-metals

1. The number of electrons in the outer shell is generally 4-8

2. Easily gain or lose valence electrons

3. Form acidic oxides whenever they come in contact with oxygen

4. High electronegative elements

5. Great oxidizing agents.
