Solution: Draw a partial (valence-level) orbital diagram, and write the condensed ground-state electron configuration for each:(a) Ba

Problem

Draw a partial (valence-level) orbital diagram, and write the condensed ground-state electron configuration for each:
(a) Ba

Solution

First, we need to determine the electron configuration for Ba (barium). The electron configuration depends on the number of electrons an atom or ion has. Since Ba is neutral, we can say that atomic number Z = number of protons = number of electrons. Barium has an atomic number of 56, so it has 56 electrons.
