A polar covalent bond because: When two atoms with different electronegativities form a covalent bond, the shared electrons are more likely to be closer to the atom of higher electronegativity rather than the atom of lower electronegativity.
When the difference between the electronegativities of two elements is in the range 0-2 (Pauling system) the bond is covalent; generally compounds between nonmetals are covalent.
polar covalent
due to increase in anion size. Iodine is larger than chlorine. see Fajan's Rules.
Yes, if one atom is covalently bonded to more than one atom at a time, it can be experiencing both equal (nonpplar) and inequal (polar) covalent bonds.
due to inert pair effect
The halides in higher oxidation state posses high charge and are smaller in size as compared to the lower oxidation state halides.Thus, in higher oxidation halides the charge/radius ratio is higher which contribute to the increase in polarisation and consequently these are more covalent.(--AK)
When Tin and chlorine combine it creates either:-SnCl2, called tin(II) chloride, stannous chloride. This is molecular in the gas phase and forms polymeric covalent chains in the solid (mp. 247 anhydrous form)), but dissolves to form Sn2+ which may hydrolyse. The electronegativity difference is only 1.2 so it would be expected to be covalent rather than ionic.A covalent molecular compound SnCl4, tin(IV) chloride, stannic chloride, tin tetrachloride.
ionic compounds are more soluble than covalent.
Cl-Cl is more covalent than H-Cl
Covalent bond is more common than ionic bond.
Covalent compounds are more flammable when compared to ionic compounds.Ionic compounds are more soluble in water than covalent compounds.for more go to: difference between . net

No, silicon can form only four covalent bonds.
Polar covalent. C is more electronegative than Si.
Because oxygen is much more electronegative than carbon, the bonding in CO (carbon monoxide) is a polar covalent.
Nucleic acids would be one example of a covalent compound with more than 3 elements. Proteins have more than 3 elements as well. Many organic compounds do, it is quite common.
