Question

Which type of bonding is present when valence electrons move within the sample?

Answer 1

Answer is: metallic bonding.

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.

Answer 2

That is metalic bonding.

That bonding is formed between the delocalized valence electrons in a metal and the ions of the metal (which are positive).

The delocalized electrons can move freely among the set of orbitals of neighbors atoms which is a characteristic of the metals.
