Metals and non-metals are two different types of materials that are naturally present.
They have different physical and chemical properties. This lesson will give you a quick guide to the physical properties of metals and non-metals with simple explanations and examples.
These properties include appearance, texture, color, melting point, boiling point, density, and more.
This is explained below.
Shiny (shiny appearance) Metal has a shiny surface.
This property is called Shine.
Example:
When polished, gold, silver and copper shine brightly.
Hardness
Most metals are hard and cannot easily break.
Example:
Iron and steel are very strong and used in the production of buildings and bridges.
Forminic (may hit the leaves)
Metals can be beaten onto thin leaves without breaking. This property is called formability. dukttility (can be retracted into wire)
The metal can be stretched into thin wires.
This property is called ductility.
Example:
Copper and aluminum wires are used in electrical wiring. Good conductors for heat and electricity
Metal makes it easy to carry out heat and electricity.
High melting and boiling points
Metals have a high melting and boiling point, so much warmth is required to switch to liquids or gases firmly.
Example:
Iron melts at 1,538°C. This is very expensive!
High density (heavy compact)
Most metals are difficult because they have high density.
Example:
Lead is a very dense metal.
Sonolor (making bells)
Metal creates bell noise when it bends.
Example:
Bells are made up of metals such as copper and bronze.
Let’s take a look at those properties.
Slippery (no gloss)
Most non-metals do not have a glossy surface.
Example:
coal and sulfur have a dull appearance.
Soft and brittle
Most non-metals are soft and can break easily.
Example:
Pressing will lightly break down coal and sulfur.
Not noticeable (cannot hit the leaves)
Non-metallic rest during hammering. It cannot be formed with thin leaves.
No ductility (not drawn into the wire)
Non-metals cannot be stretched into thin wires.
Example:
Sulfur and phosphorus cannot be treated into wires.
Insufficient heat and electrical conductors are required
Non-metals should not allow heat or electricity to pass through.
Low melting and boiling points
Most non-metals melt and cook at lower temperatures compared to metals.
Example:
Sulfur dissolves at just 115°C. This is much lower than iron.
Low density (light)
Most non-metals are light and not very dense.
Example:
Oxygen and nitrogen are gases and are very bright.
Non-Tonus (Do not make a bell)
Non-metals do not make a bell when hitting.
Fragile
Damage can break down into leaves. Ductility can be pulled into the wire with a fragment, not it can be pulled into the wire. sound
Metals and non-metals have different physical properties that create topics in different ways.
Metal is strong, shiny and good ladder, which helps to produce machines, cables and buildings.
Non-metals are soft, brittle, poor ladders that can help in insulation, fuel and medicine.
Understanding these properties will help you choose the right material for a variety of purposes!
