Question
The basic thing is that if size of atoms in a molecule than their radius is large than faral which ciill alos large implies large bond length ( 6 / w ) them:
( int 0, ) as Na has harger &ige than
( 4^{circ} ) so, ( log (2 a(x) ) bend length or distance ( 6 / omega ) Naf is greath than lif.

In molecule Naf and LiF, the distance between Na and f is more in comparison to Li and f. How we can say this? My doubt is on what bases we can say this? How to know /find distance between Na and f is more in comparison to Li and f. Plz help
