metallic character

Question

Metallic character of elements:

RankGuru · Accepted Answer

**Metallic Character** is defined by an element's ability to lose electrons (electropositivity).
1. **Horizontal Trend**: Decreases across a period (left to right) because the ionization energy increases, making it harder to lose electrons.
2. **Vertical Trend**: Increases down a group because the atomic size increases and effective nuclear charge on valence electrons decreases, making it easier to lose electrons.
- Therefore, Francium (bottom-left) is the most metallic, while Fluorine (top-right) is the most non-metallic.
