Answer: ionic
Step-by-step explanation:
A covalent bond is formed when an element shares its valence electron with another element. This bond is formed between two non metals. Example:
An ionic bond is formed when an element completely transfers its valence electron to another element. The element which donates the electron is known as electropositive element and the element which accepts the electrons is known as electronegative element. This bond is formed between a metal and an non-metal. Example:
Metallic bond is the type of chemical bond which occurs between the atoms of a metals.This type of bonding arises due to electrostatic interaction between the electron cloud of de-localized electrons with positively charges metal ions. Example:
