Question

Which statement is wrong among the following statements?
Statement 1: Nonmetal possess the property of ductility and malleability.
Statement 2: Nonmetallic elements in solid form are brittle.
Statement 3: Metal can produce ringing sound by striking.
Statement 4: Melting points and boiling points of metal is low.
Whose statement from above is correct?

• A. Statement 1 and 3
• B. Statement 2 and 3
• C. Statement 1 and 4
• D. Statement 2 and 4

Answer 1

Answer: (B)

Statement 2 and 3

Statement 1: Metal possesses the property of ductility (it can be stretched into wires) and malleability (it can also be rolled into sheets).

Statement 2: Nonmetallic elements in solid form are very brittle. They cannot be rolled into wires or pounded into sheets.

Statement 3: Metal can produce ringing sound by striking. This is because metals have very high mass density and all the atoms are extremely packed.

Statement 4: Melting points and boiling points of metal is high due to the presence of metallic bonds which are the strong attractions between positively charged metal ions and a 'sea' of delocalised electrons. These attractions must be overcome to melt metal. All of them must be overcome to boil it. These attractive forces are strong.
