प्रश्न
Among the elements of the second period, Li to Ne, pick out the element with the largest atomic size
Advertisements
उत्तर
The element with largest atomic size: Lithium (Li)
Notes
Concept Insight: Lithium has the largest atomic size since it is an alkali metal i.e., belongs to group 1 and we know that as we move from left to right in a period atomic size decreases. So lithium has largest size while fluorine has smallest size in second period.
