Q14.6P - Chemistry: Molecular Nature Of Matter And Change

Question

How are covalent and metallic bondings similar? How are they different?

Step-by-Step Solution

Answer

A covalent bond arises through electron sharing between atoms with a small electronegativity and leads to discrete molecules with specific shapes or to extended networks. In contrast, metallic bonding arises through the shared pooling of valence electrons from any atoms and leads to crystalline solids.

Step 1: Chemical bonding

The formation of chemical bonds between atoms or ions to form a respective molecule is referred to as a chemical bond. These chemical bonds keep the atoms intact in a molecule.

Step 2: Covalent and metallic bonding

• Covalent bonding results from the attraction between two nuclei and a localized electron pair. The bond that arises through electron sharing between the atoms with a small change is electronegativity.
• Metallic bonding results from the attraction between the core of metal atoms and their delocalized valence electrons.
• A covalent bond arises through electron sharing between atoms with a small electronegativity and leads to discrete molecules with specific shapes or to extended networks. In contrast, metallic bonding arises through the shared pooling of valence electrons from any atoms and leads to crystalline solids.
