What is the Lewis dot structure for I3 plus?

Answer 1

I -> 7e-

O(3x) -> 3(6e-) = 18e-

Since its an IO3- it has an extra electron

Total electrons = 18e- + 7e- +1e- = 26e-

I is the Central Atom

Each O has a single bond with 6 valance electrons and I and 2

Structure : Trigonal Pyramidal

Answer 2

[I3]- has 22 electrons and the Lewis structure is I-I-I with three lone pair electrons about the central atom, causing the electron geometry to be trigonal bipyramidal. electron hybridization is sp3d . is that what you mean for I3? it [I3]- is more commonly considered, as I3 will have a single lone electron (21 electrons). in that case, the Lewis structure would still be linear, but there would be two lone pairs and one single electron about the central Iodine atom.

btw, this violates the ocetet rule, exposing the fact that Lewis structure is too simplistic to properly handle all variations of what is actually occurring in nature. However, this doesn't imply Lewis Structure being invalid, it is still a very useful theory in predicting Electron behavior.

Answer 3

O: 6 valence electrons (3 atoms) = 18 electrons

I: 7 valence electrons (1 atom) = 7 electrons

There are a total of 25 electrons, but since it is an anion, there is one extra electron making the total electron count 26 electrons or 13 pairs.

I is the central atom, and since it is in the 5th period, it could have 5 s p d f electrons, thus it could have more than an octet. But since O is in the 2nd period of the Periodic Table, it could only have up to 8 electrons (an octet)... Let us work this out knowing the latter:

So we have 13 pairs...

And let us calculate the formal charge, which is supposed to leave with 1 negative charge:

Formal charge I: 7 valence e - (8 bonds + 0 nonbonded electrons) = -1

Formal charge O: 6 valence e - (2 bonds + 4 nonbonded electrons)(4 atoms) = 0

l :: l

O::I::O

l :: l

Answer 4

Cl

l

I-Cl

l

Cl

above is the skeletal structure of the molecule. To get the Lewis Structure, add 3 lone pairs of electrons around each Cl & 2 lone pairs of electrons to I (for a total of 28e-).

Answer 5

P3-:

P=P=P

Valence electrons: 3(5) +1= 16

Octet Electrons: 8(3)=24

Shared Electrons: 24-16=8

Unshared Electrons: 16-8=8

Place four dots (in pairs) around the outer Phosphorous atoms.

Answer 6

The Lewis dot structure for I3+ has one iodine atom at the center with a positive charge and two iodine atoms surrounding it. Each iodine atom contributes 7 valence electrons, while the single positive charge means that there are now 22 total valence electrons in the structure.
