What type of bond is formed between a metal and a non-metal?
Ionic bond
Metals have very few electrons in their outermost shell and tend to lose them to form positive ions; non-metals have nearly complete outer shells and tend to gain electrons to form negative ions. When a metal reacts with a non-metal, electrons are transferred from the metal to the non-metal, forming oppositely charged ions.
These oppositely charged ions are held together by strong electrostatic attraction, which is called an ionic (or electrovalent) bond. Covalent bonds form when two non-metals share electrons, metallic bonds form between metal atoms sharing free electrons, and hydrogen bonds are weak attractions involving hydrogen with F, O or N — none of these fits a metal reacting with a non-metal.
Hence, the answer is Ionic bond.
