Answer 2

Answer:

Explanation:

THE PHYSICAL PROPERTIES ARE AS FOLLOWS:

Physical Properties of Metals

Metals are lustrous, malleable, ductile, good conductors of heat and electricity. Other properties include: State: Metals are solids at room temperature with the exception of mercury, which is liquid at room temperature (Gallium is liquid on hot days)

Physical Properties of Nonmetals

• Nonmetals have high ionization energies.
•    They have high electronegativities.
•    Nonmetals are insulators which means that they're poor conductors of electricity.
•    They are dull, they do not have lustre like metals.
•    Nonmetals are poor conductors of heat. ...

•    They are very weak and brittle.      

THE CHEMICAL PROPERTIES ARE AS FOLLOWS:

Chemical Properties of Metals

•    The density of metals is usually high.
•    Metals are malleable and ductile.
•    Metals form an alloy with other metals or non – metals.
•    Some metals react with air and corrode. ...
•    Metals are good conductors of heat and electricity. ...
•    Generally, metals are in a solid state at room temperature.

chemical properties of Non-metals are :

Chemical properties of non-metal

The chemical properties of non-metal are given below:

• Non metallic oxides are acidic in nature.

• They do not dissolve in dilute mineral acids.

• They form stable compound with hydrogen.

• Their chlorides are completely hydrolyzed by water.

• Reaction of non-metals with oxygen: They react with oxygen to form acidic oxides or neutral oxides.

• Reaction of non-metals with water: They do not react with water (steam) to evolve hydrogen gas.

• Reaction of non-metal with acids: They do not react with acids because they are negative charged electron.

• Reaction of non-metal with salt solution: They do not react with salt solution but displaces less reactive non-metal from the salt.

• Reaction of non-metal with chlorine: They are react with chlorine to form covalent chlorides which are non- electrolytes.
