Explanation A compound can be successfully synthesized in reasonable yield only when it has considerable stability. Synthesis of C F 2 is failed because it is unstable. If we draw Lewis dot structure for C F 2 we could observe Carbon in C F 2 does not octet stability. Hence this compound cannot be prepared under normal conditions. Preparation of L i O 2 is failed because lattice energy that binds L i + ion and O 2 − ion too lower to stabilize the solid. An ionic compound must have reasonably higher lattice energy to remain stable. Preparation of C s C l 2 involves formation of C s 2 + cation. Two electrons have to be removed from caesium to form C s 2 + ion

Actinides

The elements in which the extra electron tends to enter the 5f-orbitals of (n–2)th main shell are considered 5f-block elements. They are also named actinides. Actinides include 15 elements, from atomic number 89 to 103.

A concentration cell consists of two Sn/Sn2+ half-cells. The cell has a potential of 0.10 V at 25 °C. What is the ratio of [Sn2+] (i.e., [Sn2+left-half] / [Sn2+right-half])?

Electrochemical cell potentials can be used to determine equilibrium constants that would be otherwise difficult to determine because concentrations are small. What is Κ for the following balanced reaction if E˚ = +0.0218 V? 3 Zn(s) + 2 Cr3+(aq) → 3 Zn2+(aq) + Cr(s) E˚ = +0.0218 V
