WebIonic radius is the distance from the nucleus to the outer edge of the electron cloud of an ion. The same trend of atomic radius applies once you divide the table into metal and nonmetal sections. A cation has a smaller radius than its neutral atom because it loses valence electrons. The “new” valence shell is held closer to the nucleus ... WebThere are couple of reasons for that. One is that when electrons start to fill p orbital the ionization energy goes down a little. Another is when each of 3 p orbitals have one … Web2) It has no stable isotopes. 3) The periodic law does not hold for xenon. 4) It has very low occurrence. 5) None of the above. 1.

WebThe ionic radius is less than the atomic radius because the atom loses an electron energy shell when it loses its outermost electron (positively charged or cation). When an atom receives an electron (either negatively charged or anion), the electron usually falls into an already existing energy shell, making the ionic and atomic radiuses equal. choose your own adventure dndWebThe electron affinity is the energy change for the addition of 1 mol of electrons to 1 mol of gaseous atoms or ions.
