Question

Which statement best describes the properties of metals?
A) they are shiny and bend without breaking
B) they are dull and are good electrical insulators
C) they conduct electricity well and are brittle
D) they can be flattened and do not conduct heat well

Answer 1

The correct option is A.

Metals have certain characteristics properties, they include the following: they are ductile, malleable, shiny, hard, lustrous, flexible and they are good conductor of heat and electricity. The malleability of metals refers to their ability to withstand bending and hammering without breaking. Metals are not dull, neither are they brittle, those are the properties of non metals.

Answer 2

Answer : The correct statement is, (A) they are shiny and bend without breaking

Explanation :

Metals : Metals are the elements that easily loose electrons and forms cations.

The properties of the metals :

• Generally all the metals are hard except sodium and potassium are soft.
• They are malleable that means it can be molded into different shapes.
• They are ductile that means it can be molded into thin wire.
• They are good conductor of heat and electricity.

Non-metals : Non-metals are the elements that easily gain electrons to form an anion.

The properties of the non-metals :

• They are non-malleable that means it can not be molded into different shapes.
• They are non-ductile that means it can not be molded into thin wire.
• They are poor conductor of heat and electricity.
• They are brittle in nature.

Hence, the best statement is, (A) they are shiny and bend without breaking
