In a crystal of iodine, the bonding is mainly through van der Waals forces due to the presence of weak London dispersion forces between the iodine molecules. The molecules are held together in a lattice structure by these intermolecular forces, allowing for a solid crystal to form at room temperature.

Is iodine crystal same with iodine resublimed?
Yes, iodine crystal and iodine resublimed refer to the same substance. Iodine resublimed is a purified form of iodine crystal that has been sublimed multiple times to remove impurities.
Is iodine crystal an ionic or molecular crystal?
Iodine crystal is a molecular crystal. It consists of individual iodine molecules held together by van der Waals forces, rather than ionic bonds between ions.
What test could you do on an iodine crystal to comfirm thst iodine is a non metal?
You can conduct a conductivity test on an iodine crystal to confirm that iodine is a non-metal. If the crystal does not conduct electricity, it indicates that iodine is a non-metal because non-metals are typically poor conductors of electricity.
Why is heat required to melt an iodine crystal?
Heat is required to melt an iodine crystal because melting involves breaking the forces of attraction between iodine molecules in the crystal structure. When heat is applied, it adds energy to the crystal, allowing the molecules to overcome these forces and transition from a solid to a liquid state.
When iodine is dissolved in alcohol what term is used to describe the alcohol?
When iodine is dissolved in alcohol, the resulting mixture is known as tincture of iodine.
Is iodine crystal same with iodine resublimed?
Yes, iodine crystal and iodine resublimed refer to the same substance. Iodine resublimed is a purified form of iodine crystal that has been sublimed multiple times to remove impurities.
Is iodine crystal an ionic or molecular crystal?
Iodine crystal is a molecular crystal. It consists of individual iodine molecules held together by van der Waals forces, rather than ionic bonds between ions.
Bonding in solid iodine?
In solid iodine, the bonding is primarily covalent. Iodine atoms form diatomic molecules held together by weak van der Waals forces. The electrons are shared between the iodine atoms, creating a stable structure.
What kind of bonding is silver iodine?
Silver iodine exhibits ionic bonding, where the silver atom donates an electron to the iodine atom, resulting in the formation of positively charged silver ions and negatively charged iodine ions that are held together by electrostatic forces.
What is the secondary stain in gram stain procedure?
It is crystal violet & stains all cells purple.
What difference in bonding between the solid state and gaseous state of iodine?
Iodine molecule has covalent bonds.
What test could you do on an iodine crystal to comfirm thst iodine is a non metal?
You can conduct a conductivity test on an iodine crystal to confirm that iodine is a non-metal. If the crystal does not conduct electricity, it indicates that iodine is a non-metal because non-metals are typically poor conductors of electricity.
How many non bonding pairs of electrons does one iodine atom have in carbon tetraiodide?
Each iodine atom in a molecule of carbon tetraiodide has three non-bonding pairs of electrons.
Name an element that exists in a crystal lattice at stp?
iodine
What is the action of iodine in grams stain?
Iodine is used to bind the Crystal Violet to the Gram Positive microbes.
Why is Iodine used in Gram staining?
Iodine is used in Gram staining as a mordant, which helps to bind the crystal violet dye to the cell wall of bacteria. This mordant-iodine complex forms larger complexes with the crystal violet dye, making it difficult for the dye to be washed away during the decolorization step. This allows for differentiation of Gram-positive and Gram-negative bacteria based on their ability to retain the crystal violet dye.
How do you describe the bonding of NaCl?
The bonding in NaCl is ionic, where sodium donates an electron to chlorine, forming Na+ and Cl- ions. The strong electrostatic attraction between these oppositely charged ions leads to the formation of a crystal lattice structure.
