Question

You may be "shocked" to discover that metals are good conductors of electricity. Which of the following statements best explains why metals behave in this way?

• A. Metallic bonding can be described as an "electron sea" with mobile valence electrons.
• B. Metals tend to have higher densities than nonmetals.
• C. Metals tend to have higher melting points than nonmetals.
• D. Metals tend to have rather large values for electronegativity.

Answer 1

The correct option is A Metallic bonding can be described as an "electron sea" with mobile valence electrons.

Ans : (A) Metallic bonding can be described as an 'Electron Sea' with mobile valence Electron.

Note: - In metals, the outer Electrons of atom belong to a 'cloud' of delocalised $e^{\ominus }$. They are no longer firmly held by a specific atom, but instead they can move freely through the lattice of positive metals ions. $\therefore$ Metals are good conductor of Electricity.
