A line notation is to be used to represent each of the given electrochemical cell. Concept Introduction: The electrochemical cells are often represented with a compact notation called a cell diagram or the line notation. In this representation, The oxidation half-reaction is always written on the left and the reduction on the right. A double vertical line, indicating the salt bridge, separates the two half-reactions. The substances in different phases are separated by a single vertical line, which represents the boundary between the phases. For some redox reactions , the reactants and products of one or both of the half-reactions may be in the same phase. In these cases, the reactants and products are simply separated from each other with a comma in the line diagram. Such cells use an inert electrode, such as platinum Pt or graphite, as anode or cathode or both.

[In this question, there are multiple answers to type in a "fill-in-the-blank" fashion - in each case, type in a whole number.] Consider using Slater's Rules to calculate the shielding factor (S) for the last electron in silicon (Si). There will be electrons with a 0.35 S-multiplier, electrons with a 0.85 S-multiplier, and electrons with a 1.00 S-multiplier.
