Highly selective Backlog Qs for JEE MainChemistryClassification of Elements and Periodicity in Properties
The atomic radii of Li ,   F ,   Na and Si follow the order:
Options
- ASi > Li > Na > F
- BLi > F > Si > Na
- CNa > Si > F > Li
- DNa > Li > Si > F
Correct answer
D. Na > Li > Si > F
Step-by-step solution
Atomic radii increases down the group due to increase in number of shells and decreases along the period due to increase in nuclear charge. So, atomic radii follows the order: Na > Li > Si > F
