Answer 1

Question:

Mention the differences between the physical properties of metals and non-metals​

Answer:

$\begin{tabular}{c | l} Metals & Non-Metal\\ \cline{1-2} \\Malleable & Non Malleable \\ \\Ductile & Non Ductile\\ \\ Sonorous & Non Sonoros\\ \\Lustrous& Non Lustrous\\ \\Conductors of Heat & Insulator of Heat \\ \\Conductors of Electricity & Insulators of Electricity\\\\Opaque&Transparent\\\\Solids&Solids , Liquid or Gases\\\\Example : Iron&Example: Carbon\end{tabular}$

Metals:

• Metals are Malleable.

• Good Conductors of heat and electricity

• They are usually solids except for mercury in room temperature.

• Metals are ductile.

• Metals  are opaque .

• Metals have high tensile strength.

• Metals are lustrous.

• Metals have high melting and boiling points.

• Metals are sonorous .

Non Metals :

• Non Metals are not Malleable.

• Bad Conductors of heat and electricity

• They are usually solids , liquids or gases at room temperature

• Non Metals are not  ductile or may be ductile in some cases .

• Non Metals  are Transparent .

• Non Metals are brittle solids .

• Non Metals are not lustrous except few .

• Non Metals have low melting and boiling points.

• Non Metals are not sonorous .

Definitions :

Lustrous : Lustrous means shiny nature.

Sonorous : They make sound when hit with a hard substance

Malleable : Malleable means they can be drawn into sheets

Ductile : They can be drawn into wires .
