📘 Answer
Electronegativity and non-metallic character are directly related. An element having higher electronegativity generally shows a stronger non-metallic character.
Non-metals have a strong tendency to attract electrons towards themselves. Therefore, elements with high electronegativity are generally more non-metallic in nature.
🔍 Periodic Trend
Across a period:
Electronegativity generally increases from left to right, and therefore non-metallic character also increases.
Left → Right
Down a group:
Electronegativity generally decreases down a group, so non-metallic character decreases and metallic character increases.
📊 Example
In the second period:
Non-metallic character generally ↑
Electronegativity generally ↑
Fluorine has the highest electronegativity and is strongly non-metallic, whereas lithium is much more metallic and has much lower electronegativity.
✅ Final Answer
Higher electronegativity indicates a greater tendency to attract electrons and is generally associated with stronger non-metallic character.
Electronegativity ↑ → Non-metallic Character ↑

Q. State the relationship between electronegativity and non-metallic character.
Solution: Electronegativity and non-metallic character are generally directly related. As electronegativity increases, the tendency to attract electrons increases, so non-metallic character also increases.
Q. Explain the relationship between electronegativity and non-metallic character.
Solution:
- Non-metals have a strong tendency to attract electrons.
- Electronegativity measures the attraction for a shared pair of electrons.
- Therefore, higher electronegativity generally corresponds to greater non-metallic character.
Q. Explain the periodic variation of electronegativity and non-metallic character.
Solution: Across a period, effective nuclear charge increases and atomic size decreases. Therefore, electronegativity increases and non-metallic character also increases. Down a group, atomic size and shielding effect increase, causing electronegativity and non-metallic character to decrease.
Down a group: EN ↓ → Non-metallic character ↓
Q. Discuss the relationship between electronegativity and non-metallic character with examples.
Solution:
Electronegativity is the tendency of an atom in a molecule to attract the shared electron pair towards itself. Non-metallic character represents the tendency of an element to accept or attract electrons.
Thus, both properties are closely related. An element with high electronegativity generally has strong non-metallic character.
For example, fluorine has the highest electronegativity and is highly non-metallic. Across a period, both electronegativity and non-metallic character generally increase.
Q. Explain in detail the relationship between electronegativity and non-metallic character and discuss their periodic trends.
1. Electronegativity
Electronegativity is the tendency of an atom in a chemical bond to attract the shared pair of electrons towards itself.
2. Non-metallic Character
Non-metallic character refers to the tendency of an element to attract or gain electrons and to show properties characteristic of non-metals.
3. Relationship
Both properties depend strongly on the ability of an atom to attract electrons. Hence, they generally vary in the same direction.
↓
Electron-attracting tendency ↑
↓
Non-metallic Character ↑
4. Across a Period
From left to right, effective nuclear charge increases and atomic size decreases. Therefore, electronegativity and non-metallic character generally increase.
5. Down a Group
Down a group, atomic size and shielding effect increase. The attraction for electrons decreases. Hence electronegativity and non-metallic character generally decrease.
Down Group: EN ↓ → Non-metallic Character ↓
Higher electronegativity is generally associated with stronger non-metallic character.
