The size of an atom can be estimated by measuring the distance between adjacent atoms in a covalent compound. The covalent radius of a chlorine atom, for example, is half the distance between the nuclei of the atoms in a Cl 2 molecule. The covalent radii of the main group elements are given in the figure below. WebIncreasing order of electronegativites of F, Cl, Br and I is. A. F Cl Br I. B. I Br Cl F. C. Br I Cl F. D. Cl; Br I F.
