We know that ionic bonding is the type of bond that is made between a nonmetal and a metal. In this type of union one of the elements yields electrons and the other accepts electrons.
As in this case, the metal is Lithium, we need a nonmetal to complete the union.
Let's see the options:
Beryllium is a metal.
Calcium is a metal.
Fluoride is a nonmetal.
Sodium is a metal.
After the analysis we conclude that the correct answer is Fluoride since it is the only one that is a nonmetal.
Glucose is broken down through a process known as Cellular Respiration. It goes through 3 parts: Glycolysis, Krebs Cycle, and the ETC (Electron transport chain)<span />
