Question

Y is the ionic radius of fluoride more thqn the atomic radius of flouride

Answer 1

Flourine on accepting an electron gets more electrons into its atom and since the nulear charge did not change at all as when it was flourine so now those 10 electrons could not be kept into that much space as 9 electrons as they repel more now as so they move apart from each other till they feel they can be easily held by original nuclear charge

Answer 2

there is no relation between the atomic radius and atomic number because atomic number is given to an electron for grouping it according to its similar properties and valency ....and this is true as u would have noticed elements belonging to a same group have same valency and so same chemical properties..........but atomic radius of an element is the distance between it's nucleus to the electron present in the putter most shell of the element ....it helps in finding out the inonisation of the element
