Question

Define metallic and non-metallic character?

Answer 1

Metallic character:

• The metallic character is the tendency of an element to lose electrons and form positive ions or cations.
• Alkali metals, like lithium (Li) sodium (Na), and potassium (K) are the most electropositive elements.
• Cesium (Ca) is the most electropositive element as well as stable.
• Metallic character decreases from left to right across the periods.
• Metallic character increases down the group.

Non-metallic character:

• The non-metallic character is the tendency of an element to accept electrons and form negative ions or anions.
• Fluorine is the most electronegative element.
• Non-metallic character of elements increases from left to right across the period and decreases from top to bottom.
