Want this question answered?
Atoms combine with each other by a gum which is called attrection or called bond. the bond is like a gum or fevicol . bond or this gum have many types which is depended on atomic nature who combine. if atoms nature have metallic nature ,bond types ionic bond. if atoms have partneric nature bond types covalance bond. and third other types bond called subcovalance bond.
molecule of iodine is made up of similar kind of iodine atoms .So there is no difference in the electronegativity. Hence,it forms non-polar covalent bond.
Covalent bond is formed between the two atoms (hydrogen and iodine) in HI.
Remember HOFBrINCl or (HoffBrinkel) Hydrogen, Oxygen, Fluorine, Bromine, Iodine, Nitrogen, Chlorine. They are also called Diatomic Pairs. :)
Atoms of elements have a fixed number of electrons that can bond with other atoms. Carbon has 4 electrons that can bond with other atoms. So 4 hydrogen atoms can bond with one carbon atom.
unsaturated are oils that have double bonds in their structure because there is not enough hydrogen atoms to bond with the carbon atoms. In such case, carbon atoms bond to each others to form double or triple bonds. adding iodine, saturates the oil as iodine atoms bond to carbon atoms as if they were hydrogen atoms. This is an answer to the question that should read: How does iodine affect unsaturated fats?
Iodine can bont bond with itself, and other Halogens.
It is ionic bond

think in the gaseous phase there are other forces acting atoms of iodine like inter moleculer forces due to wich bond distance increases. in case of gasous state there are no other force acting on the molecule of iodine axcept electrostatic force between two atoms of iodine . so in case of gase elctrostatic force is more than in the case of solid..

Iodine I2 is covalently bonded and the bond is non polar as the atoms at both ends are identical
No, not always. Some can exist in what's called a "monatomic state". That is, they exist as a single atom, either due to artificial separation from other atoms, or because they have no need to bond to other atoms. Atoms tend to bond to other atoms to become more stable, but atoms that are already stable tend not to bond. Examples of such are the noble gasses, which rarely bond except through synthesis.
Caesium (Cs), since has the lowest electronegativity

When a bond is formed by atoms by sharing the electrons, the bond is called a covalent bond.
