If you sketch a Lewis dot structure of I3-, you'll perceive
that the center I atom formulates two bonds, and also has three non-bonding
pairs of electrons. That's an over-all of five electron pairs - beyond an
octet. Lots of compounds disrupt the octet rule that means, but the first long-row
elements like F can't because the lower elements like iodine can use an obtainable
d-orbital to house the additional pair of electrons (sp3d hybridization), but F
just doesn't have a d-orbital that it can use.

D because these are the biggest particles, and are therefore, the most dense.
Answer: iodine 131 iodine 132 isotopes
Explanation:
Scandium? Is that what you mean?
<u>Answer:</u> The volume of barium chlorate is 195.65 mL
<u>Explanation:</u>
To calculate the volume of solution, we use the equation used to calculate the molarity of solution:

Given mass of barium chlorate = 25.0 g
Molar mass of barium chlorate = 304.23 g/mol
Molarity of solution = 0.420 mol/L
Volume of solution = ?
Putting values in above equation, we get:

Hence, the volume of barium chlorate is 195.65 mL
