Study the electron dot diagrams in Figure 1 above. Which two elements are most likely to react and form a compound? What type of compound are they likely to form?
(Li) Lithium and (F) Fluorine would create a binary ionic compound which would be lithium fluoride which would be (LiF). They would create an ionic compound because lithium is a metal and fluorine is a nonmetal. Metal + Nonmetal = binary ionic compound.
