The correct Answer is:
To solve the question regarding the attractive forces between metal ions and mobile electrons, we can analyze the options provided. ### Step-by-Step Solution: 1. **Understanding the Concept**: - In metallic bonding, metal ions are surrounded by a sea of delocalized (mobile) electrons. The attractive forces between the positively charged metal ions and the negatively charged mobile electrons are what hold the metal together. 2. **Analyzing the Options**: - **Option A: Humor** - This seems to be a misinterpretation or typo. It could refer to "humor" as a casual term, but in the context of chemistry, it does not apply. We will consider it as a potential distractor. - **Option B: Water** - Water can affect metallic bonds by dissolving some metal ions, but it does not directly weaken the metallic bond in solid metals. - **Option C: High Temperature** - Increasing the temperature provides energy to the system. This added energy can increase the kinetic energy of the mobile electrons, which can weaken the attractive forces between the metal ions and the electrons, potentially leading to melting or changes in the metallic structure. - **Option D: All of These** - This option suggests that all previous options can weaken the attractive forces. 3. **Evaluating the Correct Answer**: - Among the options, high temperature is the most relevant factor that can weaken the attractive forces between metal ions and mobile electrons. Therefore, the correct answer is **Option C: High Temperature**. ### Final Answer: The attractive forces between metal ions and mobile electrons can be weakened or overcome by **high temperature**. ---

Distinguish between Conduction electrons and ions

The attractive force between oppositely charged ions that holds ions together is called an _______ bond.

The gravitational attraction between electron and proton in a hydrogen atom is weaker than the coulomb attraction by a factor of about 10^(-40) . An alternative way of looking at this fact is to estimate the radius of the first Bohr orbit of a hydrogen atom if the electron and proton were bound by gravitational attraction. You will find the answer interesting.

According to C.F.T, attraction between the central metal ion and ligands in a complex is purely electrostatic. The transition metal which forms the central atom cation in the complex is regarded as a positive ion. It is surrounded by negative ligands or neutral molecules which have a lone apir of electrons, if the ligand is a neutral molecule such as NH_(3) , the negative and of the dipole in the molecule is directed towards the metal cation. the electrons on the central metal ion are under repulsive forces from those on the ligands. thus the electrons occupy the d-orbitals remain away from the direction of approach ligands. ltBrgt Q.
