Question
What element has the greatest change in energy between the second and third ionization energies? Sr,Cu,Te,Cl,As
Which of the following statements is NOT true?
The separation of a single molecule of the solute from the bulk solute material during the solvation process requires energy.
The solvation of solute in a solvent is always an enthalpy (energy) driven process.
Solute molecules that do not establish intermolecular interactions with the solute tend to be insoluble in the solvent.
Most intermolecular interactions are based on the electrostatic attraction between partial or full charges on the molecules.
Thank you
Explanation / Answer
1.
Sr = 38 = [Kr] 5s2.
Cu = 29 [Ar]4s^1,3d^10.
Te = 52 = [Kr] 4d10 5s2 5p4
Cl = 17 = [Ne] 3s2 3p5.
As = 33= [Ar] 3d10 4s2 4p3
among all Sr is having greatest change in energy between the second and third ionization.
2. The solvation of solute in a solvent is always an enthalpy (energy) driven process.
