Question

Although I3- is a known ion, F3- is not. (d) Yet another classmate says F3- does not exist because F is too small to make bonds to more than one atom. Is this classmate possibly correct?

Accepted Answer

Hi everyone here we have a question telling us that iodine three and browning three are known to exist as ions. However, it is hypothesized that four and three could not exist, identify the statement that would likely justify this hypothesis. A pouring as essential atom would likely cause significant electron electron repulsion due to its small size. If we look at the periodic table, we see flooring, Corinne roaming and iodine. And if we go up the periodic table it is getting smaller. So foreign is in fact much smaller than roaming or iodine. So it would cause significant electron electron repulsion due to its small size. So A. Is true. Now let's see why the others are wrong. B3 flooring atoms in the molecule could not fulfill the octet rule Florian as a central atom. Three flooring atoms in the molecule cannot fit the octet rule. The other two also do not fit the octet rule. So that is incorrect. C halogen is only exist as di atomic molecules. We know that this isn't true because iodine and bromine are also di atomic molecules. So that's not why. And Dean and above. That's not true because of its small size. It will cause significant electronic electronic polish in. Thank you for watching. Bye!
