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: 17 In this form the mass number, 35, is a stacked superscript. The atomic number, 17, is a stacked subscript. Cl" is the chemical symbol for the element chlorine. A general way to show this form is: mass number It is also correct to write symbols by leaving off the atomic number,...
