Example 1

easy
What are the three main types of chemical bonds? Give an example of each.

Solution

  1. 1
    Ionic bond: transfer of electrons between a metal and nonmetal (e.g., NaCl).
  2. 2
    Covalent bond: sharing of electrons between nonmetals (e.g., H2O\text{H}_2\text{O}).
  3. 3
    Metallic bond: delocalized electron sea among metal atoms (e.g., Cu metal).

Answer

Ionic (NaCl), Covalent (H2O), Metallic (Cu)\text{Ionic (NaCl), Covalent (H}_2\text{O), Metallic (Cu)}
Chemical bonds form because the resulting arrangement is more stable (lower energy) than separate atoms. The type of bond depends on the electronegativity difference between the atoms involved.

About Chemical Bond

A lasting force of attraction between atoms that holds them together in molecules, compounds, or crystal lattices, formed when atoms share electrons (covalent bond), transfer.
