No, metallic and non-metallic bonds are fundamentally different types of chemical bonding and do not coexist between atoms in the same compound or substance.
Metallic bonding occurs between metal atoms. In a metallic bond, valence electrons are delocalized or free to move throughout a lattice of metal cations (positive ions). The positively charged metal ions are surrounded by a "sea" of delocalized electrons, which are not associated with any specific atom. This delocalization of electrons gives metals their characteristic properties, such as high electrical conductivity, malleability, and thermal conductivity. Examples of substances with metallic bonds include metals like copper, iron, and aluminum.
On the other hand, non-metallic bonding refers to the various types of chemical bonds formed between non-metal atoms. These bonds can include ionic bonds, covalent bonds, and polar covalent bonds. In ionic bonding, one or more electrons are transferred from a metal atom (cation) to a non-metal atom (anion), resulting in the formation of positively and negatively charged ions that are held together by electrostatic forces. In covalent bonding, non-metal atoms share electron pairs to achieve a stable electron configuration. Polar covalent bonds are a type of covalent bond with an unequal sharing of electrons, resulting in partial charges on the atoms involved.
So, while metallic bonding occurs exclusively between metal atoms, non-metallic bonding encompasses a range of bonding types between non-metal atoms. They are distinct and do not occur simultaneously within the same substance or compound.
