Chemical Bonding · Covalent radius and bond length

The covalent radii of atoms A and B are

r_\mathrm{A}

and

r_\mathrm{B}

, respectively. The covalent bond length and total length of AB molecule are respectively :

(1) $(r_\mathrm{A} + r_\mathrm{B})$ , $2(r_\mathrm{A} + r_\mathrm{B})$
(2) $\dfrac{1}{2}(r_\mathrm{A} + r_\mathrm{B})$ , $(r_\mathrm{A} + r_\mathrm{B})$
(3) $(r_\mathrm{A} + r_\mathrm{B})$ , $(r_\mathrm{A} + r_\mathrm{B})$
(4) $2(r_\mathrm{A} + r_\mathrm{B})$ , $\dfrac{1}{2}(r_\mathrm{A} + r_\mathrm{B})$
