Q:

Why is it possible to bend metals but not ionic crystals?

A:

It is possible to bend metals but not ionic crystals because of the different bonding in their atomic structures.The valence electrons in metals flow freely between the atoms, while a crystal's electrons have a strong bond with their respective atoms.

The valence electrons are the outermost electrons in atoms. In metals, there is a low attraction between the atoms and their respective electrons, allowing the electrons to float freely around between the atoms. This property also explains why metals conduct electricity, as the floating electrons carry the charge. In ionic crystals, though, each electron is strongly bonded to its atom. Ions form strong bonds that can not be altered without breaking the crystal itself.

  • Q:

    Why are ionic compounds brittle?

    A:

    Ionic compounds are brittle due to the strong bond between the positive and negative ions that make up the molecules. These positive and negative bonds create crystals in rigid, lattice structures. Applying pressure shifts the alignment of the ions and results in brittleness. It takes a lot of energy to break them apart from each other.

  • Q:

    Why do solids have definite shapes and volumes?

    A:

    Solids have definite shapes and volumes because their atoms and molecules are held together firmly by the strong inter-molecular forces. At low temperatures, the kinetic energy in the solid is usually not enough to overcome these intermolecular forces, so the solid remains in the same state.

    Is silver magnetic?

    A:

    In its natural state, silver is not magnetic; its atoms have paired electrons that spin in opposite directions, thus causing their magnetic fields to be canceled out, making silver a diamagnetic material.

    What causes iodine sublimation?

    A:

    Iodine sublimation is caused by temperatures high enough to break the bonds between the atoms in its crystal lattice in the absence of pressures sufficient to keep them close to one another. At the atmospheric pressures at sea level, these conditions are met at just above room temperature, and thus both iodine sublimation and iodine deposition are readily observed. Iodine is a blue-black solid that sublimes into a purple gas.
