The core electrons are in the inner shells and do not participate in chemical reactions. The ability of valence electrons to shield other valence electrons or in partial amounts (e.g., \(S_i \neq 1\)) is in violation of Equations \ref{2.6.0} and \ref{simple}. How to easily find the number of electrons, protons and neutrons in an indium atom? The value of \(Z_{eff}\) will provide information on how much of a charge an electron actually experiences. \(Z_{eff}\) can be calculated by subtracting the magnitude of shielding from the total nuclear charge and the effective nuclear charge of an atom is given by the equation: where \(Z\) is the atomic number (number of protons in nucleus) and \(S\) is the shielding constant and is approximated by number of electrons between the nucleus and the electron in question (the number of nonvalence electrons). Electrons that have greater penetration can get closer to the nucleus and effectively block out the charge from electrons that have less proximity. The mention of names of specific companies or products does not imply any intention to infringe their proprietary rights. The proton has a mean square radius of about 0.87 1015m, or 0.87 fm, and it is a spin fermion. Indium has only three electrons in its last orbit.
