Please answer number 3 a and b
Show your work for problems 2 and 4a.
1. Revise your answer to question 1. Provide an example of an ion, and show both the
electron dot symbol for the element and the ion it will form.
2. Revise your methods report and explain how to avoid any mistakes that were made in the
first exam (ie, what did you learn from your mistakes?). Also show the ionic compound
that will form between lithium (Li) and Sulfur (S).
