Question

based on which properties can we determine an object or material as metal or non metal​

Answer 1

Explanation:

Physical Properties of Metals

Luster: Metals have the quality of reflecting light from their surface and can be polished e.g., gold, silver and copper. Malleability: Metals have the ability to withstand hammering and can be made into thin sheets known as foils.

Answer 2

Answer:

On the basis of physical and chemical properties we can determine whether an object or material is metal or non metal​ :

Explanation:

Metals:

Physical Properties:

• Metals occur in the solid state.
• All metals are stable besides with an exception for mercury that is in liquid nation in its natural shape.
• Metals also are regarded to be heavy.Metals also are sonorous. They produce a legitimate while they're rung or hit with any object.
• Metals have a excessive melting factor and a excessive boiling factor.

Chemical Properties:

• Metals corrode very effortlessly and fast.
• Metals lose electrons effortlessly.
• Most metals form metallic oxides when they react with oxygen.
• Metals have low electro-negativities, they're electropositive factors.

Non-Metals:

Physical Properties :

• Non-metals are brittle and smash into portions while beaten. Example: Sulphur and phosphorus.
• Non-metals aren't ductile so, they can't be made into skinny wires.
• Non-metals are insulators or negative conductors of power and heat due to the fact they do not lose electrons to transmit the energy.
• At room temperature, they may be withinside the nation of solids, drinks or gases.They are non-sonorous.

Chemical Properties:

• Non-metals generally tend to advantage or take delivery of valence electrons.
• When they're exposed to oxygen, non-metals react with oxygen to shape acidic oxides.
• Non-metals have excessive electro-negativity.
• Non-metals are suitable oxidizing agents.They do not react with water.
