When writing a complete electron configuration, you write the filled sublevels in order first, and then if there is a partially filled sublevel, you write it last in the sequence. You can identify the last sublevel containing electrons by finding the element in the periodic table, and determining which block and sublevel the element corresponds to. Identify the last occupied sublevel, which can be completely or partially filled, for each of the following elements. Drag the appropriate items to their appropriate bins.
