Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Metallic bonds are the attraction between
A
positive nuclei and shared electrons
B
positive and negative ions
C
positive ions and delocalised electrons
D
None of the above
Explanation: 

Detailed explanation-1: -Metallic bonds result from the electrostatic attraction between metal cations and delocalized electrons. The nature of metallic bonding accounts for many of the physical properties of metals, such as conductivity and malleability.

Detailed explanation-2: -The metallic bond is the force of attraction between these free-moving (delocalised) electrons and positive metal ions . Metallic bonds are strong, so metals can maintain a regular structure and usually have high melting and boiling points. Metals are good conductors of electricity and heat.

Detailed explanation-3: -Metallic bonding The electrons from the outer shells of the metal atoms are delocalised, and are free to move through the whole structure. This sharing of delocalised electrons results in strong metallic bonding .

Detailed explanation-4: -An ionic bond is the electrostatic attraction between positive and negative ions.

Detailed explanation-5: -The metals form positive ions whilst the non-metals, which accept the electrons, form negative ions.
