More specifically, you have to see the group wise position of Indium element in the periodic table. Zeff and Electron Shielding: Zeff and Electron Shielding(opens in new window) [youtu.be]. The concept of electron shielding, in which intervening electrons act to reduce the positive nuclear charge experienced by an electron, allows the use of hydrogen-like orbitals and an effective nuclear charge (\(Z_{eff}\)) to describe electron distributions in more complex atoms or ions. Therefore, there are various non-equivalent definitions of atomic radius. The indium atom has a total of forty-one isotopes. The results of his experiments show that each element has a unique integer equal to the number of positive charges in the nucleus of that element. How many valence electrons does a 2) You may not distribute or commercially exploit the content, especially on another website. Crystal structure: tetragonal. And to arrange the electrons, you must know the number of electrons in that element. Thus, the number of positive charges present in the nucleus of an element is called the atomic number of that element. A valence electron is an outer shell electron and may participate in the formation of a chemical bond. A neutral atom has the same number of electrons as protons. The ionic properties of the elements depend on the exchange of electrons. This leads to large differences in \(Z_{eff}\) for different elements, as shown in Figure \(\PageIndex{2}\) for the elements of the first three rows of the periodic table. Indium-113 is composed of 49 protons, 64 neutrons, and 49 electrons.
