Question

Why is atomic radius of fluorine smaller than that of lithium

Answer 1

fluorine has Smaller atomic radius than lithium because of attraction of protons with outer election . Neucleus of lithium control 1 electron but fluorine control 7 electrons that cause reduction in radius Length

Answer 2

Answer:

Atomic radius of fluorine smaller than that of lithium.

Reason : In the period atomic radii decreases from left to right across a period in periodic table. The nuclear charge increases as we proceed from left to right, thus the attraction between nuclei and outermost atom increases. This increase in nuclear charge decreases the atomic radii.
