Question

Which of the following is/are the requirements for the formation of the metallic bond?
(i) Formation of negative ions.
(ii) Formation of positive ions.
(iii) Freely moving electrons.
(iv) Sharing of electrons between two atoms.

• A. (i) and (ii)
• B. (ii) and (iii)
• C. (iii) and (iv)
• D. (i) and (iv)

Answer 1

The correct option is B (ii) and (iii)

In a metallic bond, the metal atoms lose electrons to become positively charged and these electrons flow around freely, forming an electron cloud surrounding the metal ion.
Ex: Copper wire contains copper ions(positive) surrounded by a sea of electrons.
