Explain the change of atomic size in periodic table |
|
Answer» The size of an atom is defined by the edge of its ORBITAL. HOWEVER, orbital boundaries are fuzzy and in FACT are variable under different CONDITIONS. In order to standardize the measurement of atomic radii, the distance between the nuclei of two identical atoms bonded together is measured. The atomic radius is defined as one-half the distance between the nuclei of identical atoms that are bonded together |
