Question

In metallic bonding, move freely between neighboring atoms. Metals are ductile because the forces that hold their atoms together are .

Answer 1

Answer is: Metallic bond is a type of chemical bond.

Metallic bond is formed between electrons and positively charged metal ions.

Metallic radius is defined as one-half of the distance between the two adjacent metal ions.

Metallic bond increace electrical and thermal conductivity.

Metals conduct heat, because when free moving electrons gain energy (heat) they vibrate more quickly and can move around.  

Answer 2

Answer;

Metallic bond

Explanation;

• Metallic bonds are forces of attraction that hold metal atoms together. These bonds result from the attraction between negatively charged electrons and positively charged nucleus of metal atoms.
• Metallic bond is the force that binds metals together. Metals are malleable and ductile because when a force causes metal ions to move past each other, layers of ions are still held together by delocalized electrons between them.
