"Use the covalent radii in Fig. 2D.11 to calculate the bond lengths in the following molecules. Account for the trends in your calculated values: (a) CF 4; (b) SiF 4; (c) SnF 4"
Can someone explain how to do this? Thank you

In order to find the bond length of covalent bonds you need to add together the 2 covalent radii for the elements. For a) the covalent radius of C is 77(because it forms a single bond with F in CF4) and the covalent radius of F is 58, so the bond length is 77+58= 135 pm.
The same process is used for parts b and c.
