Question

1. Distinguish between the physical properties of metals and non-metals.
2. Describe briefly the chemical properties of metals with the help of examples.
list the uses of any five metals.​

Answer 1

Answer:

Metals:These are shiny

no metals:These are non-lustrous except iodine

metals: Electropositive in nature

non metals:Electronegative in nature

metals:Have high densities

nonmetals:Have low densities

Answer 2

Step-by-step explanation:

METAL

1) physical properties:

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:

1. Easily corrodible

2. Can lose electrons

3.Form basic oxides

4.Have low electronegativities

5. Good reducing agents

NON-METALS:

physical properties:

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:

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
