Question

Why metals are good conductors

Answer 1

Metals allow electric charge to move freely through them. Metals have a sea of delocalized electrons that are able to move freely throughout the metal structure.

Please make brainliest answer I need one more <3

Answer 2

Answer is: because of delocalized electrons in metallic bond.

Substances with metallic bond conduct an electric current in liquid and solid state, because they have mobile electrons.

Most metals have strong metallic bond, because strong electrostatic attractive force between valence electrons (metals usually have low ionization energy and lose electrons easy) and positively charged metal ions.

1. Metallic bond is a type of chemical bond.  

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

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

4. Metallic bond increace electrical and thermal conductivity.  

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