Which statement describes the electron sea model for metallic bonding? a.this model involves electrons held tightly between atoms. b.this model explains all properties of metals. c.this model involves electrons moving among bands of orbitals. d.this model is the simplest model. the answer is d.

D

Explanation:

The metallic bond occurs between the several amounts of atoms of metal, or in alloys. The model that explains the bond is the electron sea model, which is the simplest model, because it explains some of the properties of the metals, and has a simple formulation.

For this model, the metallic atom loses its electrons, forming a cation, which will be immersed in a sea of the electrons lost. The attraction force between the cations and the electrons and the presence of electrons explain why the metals and the alloys are solids and conduce electricity, for example.

B) gets smaller

The concentration of hydrogen atoms is inversley related to its pH.
