Question

In general, the property (magnitudes only) that shows an opposite trend in comparison to other properties across a period is ______. 

Options

• electronegativity

• electron gain enthalpy

• ionization enthalpy

• atomic radius

Answer 1

In general, the property (magnitudes only) that shows an opposite trend in comparison to other properties across a period is atomic radius.

Explanation:

The periodic table shows that while electronegativity, electron gain enthalpy, and ionisation enthalpy rise over time, atomic radius decreases.
