An ionic bond results in an exchange or transfer of electrons between the 2 different types of atoms, most likely the metal atom and nonmetal one.
For example the compound NaF is held together by electrostatic forces of positive and negative charges due to the transfer of electrons from the sodium to fluoride atom.

Answer:
a. Tibia
b. Fibula
c. Talus
Explanation:
The ankle joint consists of three bones: the fibula, the tibia and the talus. The first two make up a vault in which the dome of the third fits. It allows, above all, forward and backward turning movements, which are flexion and extension movements of the foot. In the lateral sense, the tops of the peroneal maleolus and tibial maleolus, which are the two bony appendages that continue fibula and tibia on both sides and downward, prevent a complete movement of lateral rotation although they do allow their onset.
The talus rests on the calcaneus (the bone that forms the heel) forming a fairly flat joint, without great movement. This subastragaline joint is a source of conflict as it supports the transmission of body weight forces and governs fine movements of foot stability. When the cartilage of this joint deteriorates, an arthritic degeneration and pain occurs, which sometimes forces surgical intervention to suppress or relieve it.
