Question

Metallic Character _________ and Non-Metallic Character _______ From Left To Right in a Period.

• A. Decreases
• B. Increases

Answer 1

Metallic Character decreases and Non-Metallic Character increases From Left To Right in a Period.

Metallic Character:

• Metallic character refers to the reactivity of metal, that is how easily an element can lose electrons in a reaction.
• Metallic character decreases from left to right across the period as the outer electrons experience increasing effective nuclear charge and thus require more energy for their removal.
• Metallic character increases down the group as the outer electrons are further from the nucleus and require less energy for their removal.

Non-metallic Character:

• The elements that have the ability to gain electrons are known as non-metals.
• This non-metallic character increases on moving across a period due to the increase in the nuclear charge and the decrease in the atomic size.
• Non-metallic character decreases down the group, and the atomic radius increases thus the attraction between the nucleus and the electrons decreases so it becomes difficult to gain electrons.

Therefore, metallic Character decreases and Non-Metallic Character increases From Left To Right in a Period.
