Which of the following pairs show reverse properties on moving along a period from left to right and from top to down in a group?

Nuclear charge and electron affinity

Ionisation energy and electron affinity

Atomic radius and electron affinity

None of these

Text Solution

Verified by Experts

The correct Answer is:

Atomic radius increase from top to bottom in a group while decrease from left to right in a period. On the other hand, electron affinity shows severe trends i.e. Decrease from top to bottom in a group and increse from left to right in a period.

The main group elements complete their elctron configuration using s and p electrons in the periodic table. These elements range from the most metallic to the most non-metallic , with intermiediate properties of semi-metals, in between . The elements which occur at the two extremes of the periodic table are highly reactive and therefore , these highly reactive elements do not occur in free state, they usually occur in the combined forms.
