What is the physical state of iodine?
solid
Iodine is a nonmetallic, nearly black solid at room temperature and has a glittering crystalline appearance. The molecular lattice contains discrete diatomic molecules, which are also present in the molten and the gaseous states.

What type of bond is boron and iodine?
Because the boron atom is able to contribute three electrons, it is able to participate in three covalent bonds, whereas the iodine atoms can each form only one bond. The boron triiodide molecule has a typical trigonal planar structure.
Is i2 in its natural state?
Iodine is found in seawater, as iodide. It is only present in trace amounts (0.05 parts per million); however, it is assimilated by seaweeds. In the past iodine was obtained from seaweed….

Why is iodine a solid?
Despite intermolecular forces being a weak individual force of attraction, collectively they are very strong and the numerous forces between iodine molecules means that more heat energy is required to break these intermolecular forces and separate the molecules therefore iodine is a solid.
Is iodine diatomic solid?
Iodine is a solid diatomic non-metal that is very pungent in odor and a corrosive poison.

Is I2 aqueous?
Nearly insoluble in water but very soluble in aqueous solutions of iodides. BLUISH BLACK OR DARK PURPLE CRYSTALS WITH PUNGENT ODOUR. Violet-black crystals with metallic luster and a sharp, characteristic odor.
Is I2 a solid or iodine I?
Iodine is a chemical element with the symbol I and atomic number 53. The heaviest of the stable halogens, it exists as a semi-lustrous, non-metallic solid at standard conditions that melts to form a deep violet liquid at 114 °C (237 °F), and boils to a violet gas at 184 °C (363 °F).
Why iodine in the solid state is brittle?
Molecular solids Each iodine molecule is made up of 2 iodine atoms, held together by a strong covalent bond. Each iodine molecule is held to another by weak Van Der Waal’s forces. Low melting and boiling point due to weak forces between molecules. They are brittle.
Is iodine diatomic as a liquid?
Bromine and iodine commonly exist in liquid form, but also as diatomic gases at slightly higher temperatures, making a total of 7 diatomic elements. All of the diatomic elements are types of nonmetals. Fluorine, chlorine, bromine, and iodine are all halogens.
