Rank the following chemical species from largest ionic radius to smallest ionic radius
7nadin3 [17]

Answer:

Biggest Radii     V²⁺ > V³⁺ > V⁴⁺ > V⁵⁺     Smallest Radii

General Formulas and Concepts:

  • Periodic Trends: Atomic/Ionic Radii
  • Coulomb's Law

Explanation:

The Periodic Trend for Atomic Radii is down and to the left. Therefore, the element with the largest radius would be in the bottom left corner of the Periodic Table.

Anions will always have a bigger radii than the parent radii. When we add e⁻ to the element, we are increasing the e⁻/e⁻ repulsions. This will cause e⁻ to repel themselves more and thus create more space, increasing the radii size.

Cations will always have smaller radii than the parent radii. When we remove e⁻ from the element, we are decreasing e⁻/e⁻ repulsions. Since there are less e⁻, there is no need for more space and thus decreases the radii size.

Since Cations are smaller than the parent radii, the more e⁻ we remove, the smaller it will become.

Therefore, the least removed e⁻ Vanadium would be the largest and the most removed e⁻ Vanadium would be the smallest.

A new chemist moved into an industrial lab where work was being done on oxygenated gasoline additives. Among the additives that
marusya05 [52]

solution:

The given specta of the unknow compound of the additive gasoline in the pure state are determined from the given spectral data is

\delta 0.9 triplet Area=3H\\\delta 1.5 sextet area=2H\\\delta 3.2 triplet,area =1H\\\delta 3.5 quartert,area=2H\\form the above spectral data the structure of the compound is\\(3.5,q)(3.2,t)\\CH_{3}---CH_{2}---CH_{2}---OH\\As the compound is very sample so there is interaction between the alcoholic proton and methylene proton.
