Which one has the largest size br i i cl?
Why iodine has a largest size among ,Br,I,I-,Cl.
Which is bigger Cl or Br?
As Br is smaller than Cl; therefore, Br- have a smaller ionization energy than Cl-. In short, since the outermost electron in bromine is farther from the nucleus than the outermost electron in chloride, it takes less energy to remove the outermost electron in bromide.
Which one has the largest size BR I?
Br is placed above I in periodic table. Thus Br is smaller than I+,I,I−. Among I+,I,I− the lowest effective nuclear charge is experienced by I−. Thus it has largest size.
Which halogen has largest size?
Iodine has the largest atomic size among halogens.
Is BR bigger than F?
Negative ions are bigger than the atoms they come from. Chlorine is 2,8,7; Cl- is 2,8,8. Although the electrons are still all in the 3-level, the extra repulsion produced by the incoming electron causes the atom to expand.
…
| vdW radius (nm) | ionic radius of X- (nm) | |
|---|---|---|
| F | 0.147 | 0.133 |
| Cl | 0.175 | 0.181 |
| Br | 0.185 | 0.196 |
| I | 0.198 | 0.220 |
Which is bigger F or Cl?
The order in decreasing size would be Cl- > F- > Na+ > Li+. This can be explained by the following logic. Cl- would be the largest because it has the largest number of electrons, i.e. 18. … Similarly Li+ would be the smallest because it has only 2 electrons and therefore the least electron- electron repulsion.
Why is CL larger than Na+?
Na atoms are larger than Cl atoms because the electron cloud of Cl is pulled in more tightly by the increased number of protons in the nucleus. Na+ ions are smaller than Cl- ions because the Na+ ions have electrons in only two energy levels and Cl- ions have electrons in three levels.
Which is larger k or k+?
These are electrons with “highest energy level”. When at neutral, the potassium ion in the form of K has an electronic configuration of: … The K+ ion has its outermost electrons on the third energy level now and is size is smaller than that of K ion. Hence, K is larger than K+.
Is BR more electronegative than CL?
Check out boron: it’s less electronegative than hydrogen [2.0 vs. 2.2].
…
Carbon is More Electronegative Than You Think.
| Element | Electronegativity (Pauling) |
|---|---|
| Cl | 3.2 [3.16] |
| N | 3.0 [3.04] |
| Br | 3.0 [2.96] |
| I | 2.7 [2.66] |
Is iodine bigger than chlorine?
Answer: it a matter of atomic size of Cl-atom and I-atom. … On the other hand, atomic size of Iodine is much bigger than that of Chlorine.
Which of following is largest in size?
So S2- has largest size.
Which has smallest size?
Ionic size varies inversely with nuclear charge. Higher the nuclear charge, smaller the radii. Thus P5+ because of the high nuclear charge, has the smallest size.
Is fluorine bigger than iodine?
The larger pull from the closer fluorine nucleus is why fluorine is more electronegative than chlorine is. As the halogen atoms get bigger, any bonding pair gets further and further away from the halogen nucleus, and so is less strongly attracted towards it.

Which halogen has lowest dissociation energy?
Among the halogens, why is it that the fluorine has the lowest bond dissociation enthalpy, considering the fact that fluorine is the smallest and the internuclear distance between the fluorine molecule is least and 2p−2p overlap should also very very strong ,the bond dissociation enthalpy should have been very high but …
Which Halogen is most electronegative?
Fluorine exists as a diatomic molecule in its free state (F2) and is the most abundant halogen found in the Earth’s crust. Fluorine is the most electronegative element in the periodic table. It appears as a pale yellow gas at room temperature. Fluorine also has a relatively small atomic radius.
