Question

6. Which of the following is not true
about metals?
O Metals are ductile.
O Metals are sonorous.
Ο Ο
Metals are brittle,
Metals are malleable​

Answer 1

Answer:

All.of the given options is right in this question.

Explaination :

All.of the given options is right in this question because the properties of metals are :-

(1) High Density

(2) Sonorous

(3) Ductile

(4) Malleable

(5) Good conductor of electricity

Answer 2

Required Answer :

O Metals are ductile.

O Metals are sonorous.

● Metals are brittle $\checkmark$

Ο Metals are malleable

• Option third is not true about metals, rest of the statements are true.

Correct statement :

Metals are brittle ⌧

$\longrightarrow$ Metals are hard. And non-metals are brittle.

• Metals are hard to touch. Examples of metals include iron, copper, zinc, lead etc. Also they can't be cut easily.

• Whereas non-metals are brittle [means soft] . Examples of non-metals include carbon, Sulphur etc.

Additional Information :

Characteristics of metals :

• Metals are ductile

• Metals are malleable

• Metals are hard to touch

• Metals are lustrous [shiny surface]

• Metals are strong since they have high tensile strength.

• Metals are sonorous

• Metals are good conductors of heat & electricity.

Characteristics of non-metals :

• Non-metals are brittle

• Non-metals are soft to touch.

• Non-metals are dull

• Non-metals are weak since they have low tensile strength.

• Non-metals are not sonorous

• Non-metals are bad conductors of heat & electricity

• Non-metals are neither malleable nor ductile. They are brittle.

$\star$ Some chemical characteristics of metals and non-metals :

$\bullet$ Metals :

• Metals react with water to produce hydrogen gas.
• Metals form basic oxides.

$\bullet$ Non-metals :

• Non-metals do not react with water.
• Non-metals form acidic oxides.
