is it so? Bromine is more electronegetive than Iodine
No, nitrogen is more electronegative than iodine. Electronegativity of nitrogen= 3.04 Electronegativity of Iodine = 2.66
Iodine is lower in the halogen displacement series than bromine, i.e., iodine is less electronegative than bromine. However both chlorine and fluorine can displace bromine in sodium bromide, as they are more electronegative.
An iodine atom has one more principal energy level than a bromine atom. Therefore the radius of an iodine atom is greater than the latter.
Refering to modern Peridic Table gas which is molecule are fluorine, chlorine, Bromine, Iodine and Astatine.
The electronegativity of sodium is 0,93.The electronegativity of uranium is 1,38.A lower electronegativity is the meaning of more chemical reactivity.
chlorine is more active than bromine which is more active than iodine
No, nitrogen is more electronegative than iodine. Electronegativity of nitrogen= 3.04 Electronegativity of Iodine = 2.66
Bromine is more reactive than iodine/bromine is higher in the activity series than iodine
No. Bromine is more reactive than iodine. Therefore, bromine will displace iodine.
Bromine has more nuclear charge as compared to iodine. So, bromine easily attracts an electron and hence more reactive.
iodine has lower electronegativity than chlorine
It is because bromine is smaller in size than iodine and hence easily reacts. Another reason is that bromine is the more electronegative than iodine and hence it attracts the electrons very easily from other atoms to form bonds.
Iodine is lower in the halogen displacement series than bromine, i.e., iodine is less electronegative than bromine. However both chlorine and fluorine can displace bromine in sodium bromide, as they are more electronegative.
An iodine atom has one more principal energy level than a bromine atom. Therefore the radius of an iodine atom is greater than the latter.
Chlorine is more electronegative than iodine.
Iodine's electron configuration is 2, 8, 18, 18, 7; bromine's is 2, 8, 18, 7. At the simplest level of modelling there is one more electron shell occupying space in an iodine atom than in one of bromine.
