Question

Which statement describes the electron sea model for metallic bonding?

-This model involves electrons held tightly between atoms.
-This model explains all properties of metals.
-This model involves electrons moving among bands of orbitals.
-This model is the simplest model.

Answer 1

This model is the simplest model.

(This is the answer just took the test)

Answer 2

Answer;

This model is the simplest model.

Explanation;

• Electron sea model in metals is a model that explains properties of metals. For example the electrons move freely in the metallic structure which makes metals good electrical conductors. Drifting electrons makes metals malleable and also because cations slide easily over each other.
• The metallic bond results from the attraction between the sea of electrons and the positively charged nucleus of atoms of these metals. This model explains that cations are in fixed points within the mobile sea of electrons.
