Question

which of the following properties generally decreases along the period

Answer 1

Atomic radius , Ionic radius , electron affinity electro positivity generally decreases along the period

Answer 2

Answer:

• Atomic size
• Electropositivity character
• Metallic character
• Atomic radius
• Electron affinity

Explanation:

Atomic size:

Atomic size decreases on moving along a period from left to right due to increase in effective nuclear charge.

Electropositivity character:

Electropositivity generally decreases from left to right period.

Metallic character:

Metallic character decreases in period.

Atomic radius:

Atomic radius decreases in period as the atomic size decreases and nuclear charge increases.

Electron affinity:

It also decreases from left to right in the period.
