Which of the following property in a group decrease down the group and increase down the group respectively?
Which of the following property in a group decrease down the group and increase down the group respectively?
The correct option is A electronegativity and atomic radius
The exact solution is option (A) electronegativity and atomic radius.
Explanation
On moving down, the group electronegativity decreases. On moving down, the group atomic shell increases thereby atomic radius increases.
Explanation of option (B) why it is incorrect
As we progress through the families, the electron gain enthalpy has been less negative. As we move down a group, the atomic size, and nuclear charge increase. Increasing nuclear charge, on the other hand, has far less effective than increasing atomic size. As a corollary, the enthalpy of electron gain as well as a group's electronegativity both drop.
Explanation of option (C) why it is incorrect
In a group, atomic radius rises whilst electronegativity decreases.
Explanation of option (D) why it is incorrect
As indicated in the explanation of the option, both fall in a group (B).
The concluding statement is that option (A) electronegativity and atomic radius are correct.
