What keeps the ions in their fixed positions?
Ionic bonds hold the ions in fixed positions within a crystal lattice. These bonds are formed through the electrostatic attraction between positively and negatively charged ions. The strong attraction between oppositely charged ions results in a stable crystal structure.
What is the motion in solid iodine?
In the solid state, iodine atoms vibrate around their equilibrium positions due to thermal energy. This motion is known as lattice vibrations or phonons. The overall motion of iodine atoms is restricted to a fixed position within the solid lattice structure.
How cesium chloride conduct electricity in the solid state?
Cesium chloride conducts electricity in the solid state due to the movement of ions. In the solid state, cesium chloride exists as a crystal lattice structure where cesium cations and chloride anions are held in fixed positions. When an external electric field is applied, these ions are able to move within the lattice, allowing for the conduction of electricity.
Why do ionic compounds conduct electricity only in molten state?
Ionic compounds conduct electricity only in the molten state because the ions are free to move and carry electric charge. In the solid state, the ions are held in fixed positions within the crystal lattice, preventing them from moving and conducting electricity.
What happens to the atoms in a liquid as it freezes?
As a liquid freezes, the atoms in the substance will slow down and come closer together, forming a crystalline structure. This process releases energy in the form of heat. As the temperature decreases further, the atoms become locked into fixed positions within the crystal lattice, resulting in the solidification of the substance.
What is the 3-dimensional pattern that ionic compounds are bonded in?
Ionic compounds are bonded in a repeating, three-dimensional lattice structure called a crystal lattice. This lattice is formed by the strong electrostatic attraction between positively and negatively charged ions held together in a fixed, repeating pattern.
Why do the ions in lattice of a sodium crystal stay in place?
The ions in the lattice of a sodium crystal stay in place due to the strong electrostatic forces of attraction between the positively charged sodium ions and the negatively charged electrons. These forces create a stable structure where the ions are held in fixed positions in a repeating pattern. Any movement of the ions would require a significant amount of energy to overcome these forces.
Why is a crystal incompressible?
A crystal is considered incompressible primarily due to its tightly packed atomic structure, where atoms are arranged in a fixed, orderly lattice. The strong intermolecular forces within the crystal lattice resist changes in volume when pressure is applied. Additionally, the rigidity of the bonds between atoms limits their ability to move closer together, making it difficult to compress the crystal further. As a result, crystals typically exhibit low compressibility compared to other materials.
Explain why the position of hydrogen can not be fixed exactly with respect to Mg Zn Pb Cu and Ag?
The position of hydrogen is not fixed exactly with respect to Mg, Zn, Pb, Cu, and Ag because these elements form ionic bonds with hydrogen, leading to a more dynamic interaction where hydrogen can have varying positions within the crystal lattice. Additionally, the smaller size of hydrogen compared to these metals allows for greater flexibility in its location within the crystal structure.
What is difference between sessile dislocation and glissile dislocation?
a sessile dislocation has a burger's vector that does notlie in the primary slip plane of the crystal, so it is immobile.a glissile dislocation has a burger's vector that doeslie in the primary slip plane of the crystal and thus is able to move in that plane.
