Answer:
The correct answer is - ionic bond.
Explanation:
Ionic bonds are the bonds that are formed when an atom transfer its electron to the other atom and forming ions that become electrically charged that attracts each other and form bond between them.
Given the picture showing the ionic bond formation as sodium transfers one electron to the chlorine ion and becomes electrically charged and therefore electrically attracted to one another to form an ionic bond.
Thus, the correct answer is - ionic bond.
