Why metal do not form covalent bond?

It's easier for them to release few electrons from the outer shell to obtain a noble gas configuration rather than consuming several ones. However, the difference between an ionic and a polar covalent bond is always fringe. Again, it's not true that metals don't form covalent bonds at all.

Keeping this in view, what type of bonding is in metals?

Metals form giant structures in which electrons in the outer shells of the metal atoms are free to move. The metallic bond is the force of attraction between these free electrons and metal ions. Metallic bonds are strong, so metals can maintain a regular structure and usually have high melting and boiling points.

Is metallic bonding only between metals?

Metallic bonding is the strong attraction between closely packed positive metal ions and a 'sea' of delocalised electrons. The attraction between the metal ions and the delocalised electrons must be overcome to melt or to boil a metal. These attractive forces are strong, so metals have high melting and boiling points.

Can metals bond with metals?

Metallic bonds can occur between different elements to form an alloy. In contrast to electrons that participate in both ionic and covalent bonds, electrons that participate in metallic bonds delocalize, forming a sea of electrons around the positive nuclei of metals.
