प्रश्न
Among the elements of the second period, Li to Ne, pick out the element with the highest electro negativity
उत्तर
The element with highest electro negativity: Fluorine (F)
Concept Insight: Fluorine has highest electronegativity as we know that electro negativity increases along a period due to decreasing atomic size and increasing nuclear charge.
