An ionic bond is expected between K and Br.
Th bonding in potassium chloride, KCl, is ionic. The crystal contains potassium ions, K+ and chlorine anions Cl-
In covalent bonding, atoms share electrons to achieve a full outer shell. This contrasts with ionic bonding, where electrons are transferred. One phrase specific to covalent bonding is "electron sharing."
Covalent bonding is found in all molecular substances. In covalent bonding, atoms share electrons to achieve a more stable electron configuration. This results in the formation of molecules.
The bonding in KI would be ionic, as potassium (K) is a metal and iodine (I) is a nonmetal. In ionic bonding, electrons are transferred from the metal to the nonmetal, resulting in the formation of ions with opposite charges that attract each other to form a stable compound.
In science, I refrain from making absolute statements. My research has not revealed that copper has a bonding configuration other than metallic. So, I would say one kind of bonding for now. Others can correct me.

Non metals generally form anions. They gain electrons during ionic bonding.
