Question

Write a note on metals, Nonmetals, Metalloids, and noble gases.

Answer 1

Metals:

• It is a solid material that conducts heat & electricity, hard, shiny, malleable, fusible, and ductile.

Some of the important characteristic properties of metals.

• Melting points that are really high.
• Excellent electricity conductors, Copper, Aluminium, Silver, Gold, etc are examples.
• They are excellent heat conductors, Copper, Aluminium, etc. are examples
• A lot of density example iron, Osmium.
• Malleable For example silver, gold, etc.
• Ductility, For example, silver, and gold.

Non Metals:

• Non-metals are bad conductors of electricity and heat. They lacked all metallic attributes.

Some of the important characteristics of non-metals.

• Non-malleable and non-ductile materials.
• They are poor heat and electricity conductors.
• There is no metallic shine to these, and they do not reflect light.
• These are gaseous at room temperature. Example Oxygen, Nitrogen, etc.

Metalloids:

• They are defined as chemical elements whose physical and chemical properties fall in between the metal and non-metal categories.
• Metalloids are semiconductors in nature.

Some of the important characteristics of metalloids

• Metalloids have the appearance of metals but behave more like nonmetals.
• They have the electronic band of a semimetal or semiconductor.
• These are glossy, brittle solids having intermediate to good electrical conductivity.
• Examples Silicon, and Boron, are common examples of metalloids.

Noble Gases:

Noble gases are inert in nature as they are the most stable elements in nature.

Some of the important characteristics of noble gases.

• Under normal conditions, noble gases are colorless, odorless, tasteless, and non-flammable.
• They were originally referred to as group zero in the periodic table since their valence was thought to be zero.
• Their atoms could not mix with other elements to make compounds.
• Examples are Helium, Argon, Neon, etc.
