The attractive interactions between cations and mobile electrons in metallic solid is called

Question

In the following species, how many species have the same magnetic moment?
(i) Cr\(^{2+}\)
(ii) Mn\(^{3+}\)
(iii) Ni\(^{2+}\)
(iv) Sc\(^{2+}\)
(v) Zn\(^{2+}\)
(vi) V\(^{3+}\)
(vii) Ti\(^{4+}\)

Answer 1

Step 1: Understanding the Question:
The question asks to identify the type of chemical bond characteristic of metals.

Step 3: Detailed Explanation:
- Ionic bond: Attraction between oppositely charged ions (\( \text{e.g., Na}^+ \) and \( \text{Cl}^- \)).
- Covalent bond: Shared pair of electrons between two atoms.
- Dipole-dipole interactions: Between polar molecules.
- Metallic bond: Described by the "electron sea model," where metal atoms lose their valence electrons to form a common pool of delocalized "mobile" electrons. The electrostatic attraction between these positive metal kernels (cations) and the sea of mobile electrons is the metallic bond.

Step 4: Final Answer:
The interaction is called a metallic bond.

The attractive interactions between cations and mobile electrons in metallic solid is called
