Valence Electrons:The number of {eq}{{\rm{e}}^ - } {/eq} acquired by the atom's highest energy shell (or outermost shell) is termed as its valence electrons. This number may or may not be equal to the valency of an atom.Answer and Explanation: ...
Write the electron configuration for the Te^{-2} ion. Determine which noble gas has the same electron configuration as Te^{-2} ion. Write the electron configuration for the below element by using the symbol of the previous noble gas to ind...
