Question

Born Haber cycle is used to determined:
A) Electron affinity
B) Lattice energy
C) Crystal energy
D) All the above

Answer 1

Hint: We must have to know that the halogen is the most electron affinity group in the periodic table. Halogen is also the most electronegativity group in the periodic table. The ionisation energy of the halogen is very less compared to other groups. In halogen from top to bottom, electron affinity decreases. Chlorine is the highest electron affinity species in the periodic table, because the size of the fluorine is very small compared to chlorine. But, the electronegativity value of fluorine is high compared to the electronegativity value of chlorine.

Complete answer:
As we know that the electron affinity can be calculated by using Born Haber cycle.
Lattice energy can be calculated by using Born Haber cycle.
Crystal energy can be calculated by using Born Haber cycle.
Born Haber cycle is used to determine the electron affinity, lattice energy and crystal energy.
According to the above discussion, we conclude Born Haber cycle is used to determine the electron affinity, lattice energy and crystal energy.

Hence, the option D is the correct answer. Because all the options match with the question.

Note:
As we know that in chemistry, periodic tables play a vital role. In the periodic table there are totally \[118\] elements. In the periodic table there are totally \[18\] columns and \[7\] rows. The columns are called groups. Hence, \[18\] groups in the periodic table. The rows are called periods. Hence, totally \[7\] period in the table. Each and every element having a specific symbol in the periodic table. Each element having a specific position in the periodic table, that position is dependent on the physical and chemical properties of the element.
