Question

Metals are different from rocks, gases, salts, acids and bases. They have special properties, such as metallic lustre, conduction of heat and electricity and imparting colours to flames. These special properties are caused by the presence of mobile electrons in a structure with a special chemical bond. Can you identify it?

• A. The hydrogen bond
• B. The ionic bond
• C. The covalent bond
• D. The metal bond

Answer 1

The correct option is D The metal bond

The chemical bonding that holds the atoms of a metal together. Metallic bonds are formed from the attraction between mobile electrons and fixed, positively charged metallic atoms. Whereas most chemical bonds are localized between specific neighboring atoms, metallic bonds extend over the entire molecular structure.

So the question is telling about Metallic bond and hence option D is correct answer.
