Metallic bonds are formed when the charge is spread over a larger distance as compared to the size of single atoms in solids. Mostly, in the periodic table, left elements form metallic bonds, for example, zinc and copper. Because metals are solid, their atoms are tightly packed in a regular arrangement. how to reset my garmin gpsWebMetallic bond is formed by sharing of electrons between many atoms A metallic bond is pretty different from covalent and ionic bonds, but the goal is the same: to achieve a lower energy state. Instead of a bond between just two atoms, a metallic bond is a sharing of electrons between many atoms of a metal element. Hence option B is correct. how to reset my galaxy phone
