Question

The diagram above represents four cations, all shown to the same scale. Which cation would be predicted by Coulomb's law to have the strongest ion dipole attraction to water and why?
A Li⁺, because it is the smallest group 1 metal ion.
B) Mg², because it has the largest charge to-size ratio.
c Na'', because it has the smallest charge to-sice ratio;
D) Ca²⁺, because it is the largest group 2 metal ion.

Answer 1

The cation that would be predicted by Coulomb's law to have the strongest ion-dipole attraction to water is Mg²⁺, because it has the largest charge-to-size ratio.

What are cations?

Cations are positively-charged ions that are formed when metal atoms lose electrons.

The size of the charge on a cation describes the number of electrons the metal ions loses.

The size of the charge of a cation will determine the strength of the attraction between the ion and another charged particle.

According to Coulomb's law, the strength of the attractive force is proportional to the charge and inversely proportional to the square of the distance between the charged particles.
