Once you have filled in all the gaps on a separate sheet of
paper, enter the four missing element symbols in the first row of
the table into the answer box below.
Learning Goal: This question reviews the format for writing an element's written symbol. Recall that written symbols have a particular format. Written symbols use a form like this: CI In this form the mass number, 35, is a stacked superscript. The atomic number, 17, is a stacked subscript....
