why BiF3 is ionic whereas other trihalides are covalent in nature?
Can you please illustrate that HCl is polar or non-polar? Briefly illustrate it.
Average covalent radii can be assigned on the basis of molecular structures. The accumulation of structural data by spectroscopic studies and both electron and x-ray diffraction studies allows one to investigate the possibili
